Not just #4, all of them
It's much easier to do prep work when you have a social safety net to keep you clothed, housed and fed while you're prepping.
It's much easier to place yourself in a situation where the opportunity can find you if you know that if opportunity doesn't find you, you'll be ok.
It's much easier to take a gamble that a bunch of hard work will lead to a fantastic opportunity if the cost of it not leading to an opportunity is very low.
