” If you can’t figure out how to do a proof of concept for you business for under $500 bucks you don’t need more resources, you need to be me resourceful.” – Andrew Anderson
Borrowed money can make you both lazy and stupid.  Go deliver pizzas and use that money. You will spend the money much more wisely and engage your brain in ways that will better server you.  There is no need to sell your soul.  I am not saying you never borrow money or get investors, but only do so judiciously.
