Can I pose what I would argue is a more difficult question to deal with?
How are you going to deal with looking back in years to come wondering what if, or if only?
There are two ways to look at it:
a) I can't raise the money
b) How can I raise the money
With a) the attitude is negative and an acceptance of defeat follows, with b) the mind is encouraged to be creative and find a solution.
Be positive you are already with option b).
