2 things - I live a simple life, and I never use credit. A lot of people have a lot nicer material things than me, but few have the freedom I do. It also doesn't hurt that I was sticking money into a coinbase account just because I needed a place to keep it and I jumped out at around $3500 having bought in at around 700. I get a little sick when I look at what it would have looked like if I had waited until it hit $20k but I made my nut so I can't complain.
But seriously, eliminate all your debt is my #1 piece of advice. It will increase your net worth by whatever your interest rates were! Even before I made some money on BTC I only worked sporadically. With no debt I could work hard for 2 years then quit and go to Africa for six months before coming home and working again.
I will never buy a new car or own a swimming pool but I'm fine with that because I live a happy, low stress life by learning to be content with having enough and seeing everything as a blessing.
