Getting a paycheck means surrendering your ability to wake up and live your life based completely on your own internal clock, and it can be a big drain on your mental health and physical well being. There are ways of charging your battery, but it's not always possible without risk and/or sacrifice if you weren't born rich or somehow otherwise financially lucky.
Health is wealth too though... We're usually born with a "glass full of water" that represents our health - mental and physical health. Over time we drink from that glass until it's gone... Once you burn out, you're toast. It's important to always be cognizant of where your water supply is, and to try to stop letting people drink from your glass before it completely runs dry... If you're lucky, you'll turn your water into a nice vintage wine.
Best case you keep your work habits and can continue working on your hobbies like you did work previously, but worst case it will all look like those weekends.
Edit: A side note being, between the changes to work culture and me gaining the experience to be more desirable to work places, I’ve managed to move to a more flexible remote position that gives me a fair bit of control over my day to day. This has definitely increased my ability to be productive in my off time, due to the lowered stress on my general energy levels.
