That's a big one. I'd say if you want to be rich (and it would be nice to have a definition of that, BTW), stay far away from high-interest credit cards and don't buy anything that you can't pay cash for.
I agree with you, credit cards are annoying in life with monthly interest, oh, oh, oh super bad.
I am now no longer modeled in my life with a credit card, everything is better.
I'd better focus on investing in Bitcoin in the future maybe 2 or 5 years will come.
Everyone can become rich, on the grounds that someone is not involved in monthly payments of interest that swells every month.
