If you have plans to start a dream business that requires a capital of  $20,000 and you were able to make a savings of $15,000 which obviously isn't enough to start up the business, what would be your decision or advice?

1. Invest the $15,000 into a smaller business hoping that the returns will yield the remaining $15,000 in a short period. Note that this has the potential of failing and wasting the already-saved  $15,000.

2. Keep the $15,000 while doing other work that will yield the remaining money over a long period.

Would love to see your input or a better suggestion apart from the ones I pointed out above.

This is the typical situation a friend finds himself and we are just brainstorming in what best to do.
