I do think there are a lot of things you can due to get probability more on your side:
- Keep your eyes open for opportunities and look for the upside ("be optimistic" is the woo-woo version), but it's been proven in experiments that you'll catch things others won't
- Only keep friends around you that actually support you. It's really hard to try to make life changes when people are constantly telling you you can't or shitting on your parade.
- Start making analytical choices. Certain fields pay more than others. Certain businesses treat their employees better than others. A lower position at a better company will increase your probability of "bumping" into those people who might be life changing.
- Learn about probability (Fooled by Randomness is a good start). If you constantly expose yourself to more chances of success, _odds are_, you'll start to find more of it.
