NEW YORK ( TheStreet) -- What do the best retirement savers have in common? Another other attributes: a positive outlook, a commitment to saving today for tomorrow and the ability to "envision" a comfortable and secure retirement. If there was one word that best describes the top savers, it might be "confidence," according to an annual retirement survey from BlackRock, the New York investment management firm. "When workers feel empowered, confident and positive about the savings process, they will actually save more for retirement than workers who don't feel that way," says Chip Castille, managing director at BlackRock's U.S. and Canada defined contribution group. BlackRock leads off its survey with some disturbing, but not uncommon news: Americans just aren't saving enough. While BlackRock advises workers to save at least 15% of their salary toward retirement, few do. According to the study, about 65% of Americans save 10% or less, and 28% save 5% or less. retirement goals. "Vision." The best power savers can actually see themselves enjoying retirement. Those workers who don't share the vision are in for an uphill climb.

Those workers who ask for professional help were much more likely to be power savers, BlackRock reports. So there you go. If it's a comfortable retirement you want, be confident, be positive, track your progress regularly, and check with a financial services professional on a steady basis. Saving 15% of your annual income every year won't hurt either.
