Good list, but here's my two cents regarding this topic. The thing is there's nuances when it comes to buying expensive things. To me, buying expensive shit as a form of reward every now and again, is totally good and permissible, at the end of the day, you put in the effort and the hours that lead you up to that level of wealth, you can't just work and not live your life. Buy expensive shit as a form of reward, treat yourself and your day ones to new experiences, make the most out of the money you made. Money is made to be spent, not to be hoarded after all.

And of course, protect your money-making machine. You can't just quit it or leave it hanging out in the open as soon as it served its purpose and had made you wealthy already. Keep learning new things related to that craft, become more versed, protect your income and your income-maker, and you'll go far my friend!
