More money, more time, more experience, or better contacts are all variables that would help in realizing an intersectional idea, we imagine. They do help, obviously, but not necessarily by decreasing the risk of failure. These resources are all factors that can help us in what we can accomplish, but they do not increase the chances of it succeeding, since with more resources we will try to accomplish more.
More money leads to greater spending. Having greater experience or better contacts means relying more on them to get things done.
What you need is the minimum amount of resources - there's no point in waiting!
