You read this blog for one of two reasons:
1) You want to make a decision
2) You want to avoid a decision
Either option is acceptable. But you need to analyze which is your reason. Because that is the first decision of the forum.
A hint that you are in Category #2: you think you need a detailed, bullet-proof business plan, protected by a nice binder, before you begin. Hint you might be in Category #1: you have tried building a business that either succeeded or failed.
Please don't ignore this issue as something trivial to fill blog space. Think for 7 minutes, decide where you stand, and move forward.
