If you don't do anything, then there's nothing that going to change your life, I'm sure that's the point and people who have that nerve risking things to change up or try to make something differently will have that equal chance in making its way to success, it's not all but most of those who take the risk and gamble with fate are those who experienced good results.
They are likely to make changes, the power of self-will give them that opportunities to find the comfort that they are aiming.
I would say that you need to keep improving to keep pace. If you stop improving then your life will change, for the worse, slowly.
That's why you need to take risks, see what works, and push forward. If you just look at life, then you'll just fade away into oblivion.
Some things won't work, others will. Keep pushing, and you will endure.
In gambling in particular though, it's all rigged against you, so you should probably only consider it as entertainment money.
