NEW YORK ( TheStreet) -- Some career experts equate managing your career with running a marathon. Like a long-distance runner, career professionals need to train, build endurance and take a long-term view of their working years. Also like a marathon, there's a danger of "hitting a wall" with your career. Long-distance runners call that "bonking" and dread the so-called middle miles of a race, when the chances of hitting that wall are highly likely. Dan Steenerson, a self-described professional achievement expert, has some good, sound advice for career professionals who may be feeling bonked themselves these days. He says that succeeding in business and in your career is very much like running a marathon. Sure, you know what you want and are anxious to meet your professional goals. But between the start and finish of that race you'll face a great deal of adversity, and how you handle that adversity will directly affect when or even if you'll finish that race, Steenerson says.
