Talk it up
The first phase in realizing your vision is to share it with friends, family and other people whose skills and savvy you respect.
Feedback strengthens your idea and makes you more likely to see the project through.
How to do it: At surveymonkey.com, create questionnaires about your potential business for friends, acquaintances, Facebook connections and anyone else whose opinion you value. Then e-mail the survey to your contacts and reap the benefits of your own market research for free! You might learn that your assumptions about the going rate for, say, life-coaching sessions, were off the mark, or that people would pay more if the coach came to their home.
