1) financial independence is great, but you could also die tomorrow. Make sure you understand what your most important values and priorities are, and don’t put them off in favor of more future wealth.
2) health is wealth, don’t ever sacrifice health for more savings. I promise it won’t be worth it.
3) relationships are wealth. Don’t sacrifice the people that matter to you for a little bit more savings. In my own life this meant going from spending very little on traveling to see old friends to quite a bit traveling to see old friends.
4) it’s often much easier and more enjoyable to increase your pay 25% than it is to decrease your spending 25%. Most people are actually not good at navigating “how do I get paid more per hour worked” and a little bit of brainstorming and long term planning in this department can take you leaps and bounds further financially than penny-pinching.
