Investment of Time/Energy/Effort may work, or it may not work, but you have to assume that it will and be hopeful.
Also, only risk that which you can afford to lose. Don’t risk it all. Never go to zero. Always have a fallback plan, safety net. Never risk it all. Spend some resources on the safety net, fallback plan that will allow you to go for the moonshot. Also, make sure you rest & rejuvenate plenty because it’s a long long long game. You have to make sure that you don’t burn out, because moonshot success is probabilistic & may or may not come, at all. So resting and relaxing in a timely manner is also very important.
