Not sure what being a millionaire has to do with avoiding burn out. There are plenty of wealthy people who still burn out. If you’re burning yourself out solely for “getting rich” you should probably buy lotto tickets instead.
If you are rich you’re burning out by choice. Having to go through something like long workdays because you want to is a completely different experience than doing so because you have to.
I never understood why people keep working once they have accumulated enough to not have to work anymore.
