NEW YORK (TheStreet) -- First impressions matter, and so do your first few weeks in a new job. It's never too early to let your boss know that hiring you was the best decision they ever made. Here are the top 10 ways to win over your boss in your first 30 days on the job.

1. Learn to anticipate your boss' needs

Pay attention to your boss' day and see where they may need help, suggests Julie Hochheiser Ilkovich, career expert and co-founder of Masthead Media.

"If your boss has a meeting every Tuesday morning at 9 and you notice that they're always late getting coffee, volunteer to pick up their coffee that day," she says. "You'll be amazed how much credit you can earn just by giving your boss what they need before they realize they need it."

By figuring out how your boss likes to operate, you establish trust early on, says Joe Ungemah, vice president of talent solutions at CEB.

"Every time you can anticipate a need, you're decreasing your boss' stress level and strengthening your relationship," he says.

2. Figure things out for yourself

Try to understand all daily tasks and projects before you go to your boss with a million questions, Hochheiser Ilkovich suggests. Your boss doesn't want to feel like they're doing your work for you.

"Many managers' biggest complaints are that employees interrupt them all day popping into their office or asking questions via email," she says. "A lot of what you're curious about can be figured out on your own, or by asking someone else."

Of course you will have questions your first few days on the job, but try to save all non-urgent questions for a scheduled meeting time.

3. Take on anything you're asked -- even if it's not your job

The words, "That's not my job," should never come out of your mouth, Hochheiser Ilkovich says. The best way to show you're committed to your new job is to step up to help out with any project that comes your way.

"You're going to be approached to do jobs that aren't necessarily within your job description. Take them on with grace," she says.

As you move past your first month or two on the job, you can hone your job description with your manager, but for now, don't turn down any opportunities.

4. Research the company

"There's no excuse for not having a significant amount of knowledge about the company and role you're walking into," says Kent Burns, president of Simply Driven Executive Search, an affiliate of Sanford Rose Associates.

It takes just a few moments of your time to research your new company on the Internet and read up on the industry, the products, the competitors and the strengths and weaknesses you'll be working with.

"Lack of preparation will kill you," Burns says.

If your company is publicly traded, check out the most recent annual report, suggests Judy Robinett, entrepreneur and author of How to Be a Power Connector.

"In the annual report, the company will be very clear how they are going to grow and what their broader vision is," she says. "You should be able to speak intelligently about how you can contribute to that vision."

5. Be humble

Let's face it -- in your first few days on the job, you have a lot to learn. Instead of spouting off rapid-fire questions or comparing your new job to your old job, sit back, listen and learn, Burns says.

"Demonstrate intellectual curiosity. Show that you care," he says. "You're informed but you're humble. Yes, you have a lot to bring to the table, but you also need to hear what others have to say and learn from people who have been doing this for longer than you have."

6. Be there

In today's mobile society, we can work from most anywhere, but in the first 30 days on the job, people need to see you, Burns says.

"When I see that one of my new employees is beating me to the office in the mornings, I think, this guy is really digging in, he's really dedicated."

Even if you're expected to be independent in your new role, it's still a good idea to spend some time in the presence of someone who knows how to do it, he says.

7. Know your role

Figure out who your customers are and how your role fits into the department as a whole -- even the entire company, Burns says.

"You have to demonstrate a desire to understand the role you're playing in this movie," Burns says. "We all think we're the star, but you do your job better when you know what people need from you."

Don't just think about yourself -- think about the bigger picture.

8. Be a team player

Don't be a loner, Robinett says.

"Don't try to be the smart person off in the corner. You may have gotten rewarded for that in college, but nothing really great happens without a team in the corporate world," she says.

Volunteer for projects that let you see the political structure of your new company. As you're working, figure out who the key players in your organization are, and what makes them successful.

9. Show up 10 minutes early for everything

It may sound trite, but when you show people you respect their time, they respect you, Robinett says.

"When you're there on time, ready to work, it signals dependability and reliability," she says. "You don't have to show up 30 minutes early and look overeager, but 10 minutes is good. It shows you can be counted on and that you know how to prioritize."

10. Get to know your team, identify a mentor

Don't wait for everyone to introduce themselves; take the initiative to meet your new colleagues, especially those who work for the same manager, says Amanda Augustine, job search expert for

"They can help you get up to speed quickly by decoding any unwritten rules within the new group and explaining your boss' management style," she says.

When you're getting to know everyone, identify a mentor. Befriend someone on the team who's been with the company for a while and is thriving.

"This person can teach you the ins and outs of the place, help you navigate corporate politics and introduce you to the right people and resources to move your career along," Augustine says.
