I've had many active and enthusiastic business team members that were their own worst enemies because they exhibited classic "flea on a griddle" behavior pattern and jumped around chasing one business opportunity today, and then another one tomorrow without ever putting in enough sustained and focused effort to reasonably give themselves a chance to succeed at any of them.
I can really relate to this situation since I briefly fell prey to this same "dog in a meat market" syndrome when I first started my own home based business a few years ago. I caught myself trying to chase several different opportunities at once and not being very successful with any of them.
There are so many home business opportunities (some real, some not) that it takes real personal discipline to avoid scattergun approach...you know, throw enough against wall and something is bound to stick. In early going, it is really important to resist this temptation and to stay tightly focused on a single business.
Some will argue that "I don't want to have all my eggs in one basket". To those people I say, diversification is fine, but only after you have achieved solid success with your initial business. A premature attempt at diversification will quite likely cause a loss of focus and actually slow down your success rate.
