When you are unwilling to work hard.
When you have no 5 year plan.
When you love your current job.
When the entrepreneurial ideas you have do not match your personality type
When you think it will be a breeze.
When you are vague about your next step
When you have no idea what your strengths are.
When you have no savings at all.
When you are only doing it for money.
When you have little that interests you other than your "day job".
