If you aren't already the joiner type, don't expect to change and become one when you start your own business. I don't like reinventing the wheel. The first thing I do when faced with a problem is to look around for someone who has already solved the same dilemma. I work on things myself for a while and look for outside help if I get stuck. I take pride in working out my own solutions to my own problems.
Effective businesspeople get the best answer as quickly as possible.
I'm able to get a number of things underway at once, dividing my time between them. I'm able to switch my attention to the hottest item and then return to the others without losing much momentum. In fact, I enjoy the variety of working this way. I find tasks yield to concentrated effort. I like to work hard on one thing until it's completed, then move on to the next item.
