Whats more important? Size of the target market or Passion for an idea.
joez: C) is two very different things. As previous articles/threads (try google search) have suggested, quitting because you hate your job is not the right place to start but maybe good motivation to take the final leap. The satisfaction of seeing something you built from the ground up can be satisfactory and keep you motivated.I don't know about D). I don't know what you are imaging about the lifestyle but all of it is hard (and hopefully enjoyable) work. If you are looking for less or easier work, look elsewhere.I think you need both A) and B) to the extent they feed off each other and when your not hitting on cylinder A) for motivation, you are hitting cylinder B) and vice versa.I didn't see anything on target market, but from a business perspective... Investors are going to ask you about this.
