Mustard,
I started my first enterprise when I was 16, Xpert Minds, a mentoring agency for teenagers. Second soon after that. Now I am on to my third attempt slated to launch during first quarter of 2007.
I penned my experiences and observations about this topic -
our world: OK You Want To Be An Entrepreneur But Are You REALLY Ready For It?
In nutshell it suggests a self-assessment before you start;
- Are you ready to slog?
- Do you have good energy levels?
- Are you a good finisher?
- Are you motivated enough to do it?
Hope this helps.
