As we enter the crypto mooning phase (just before the crypto mars-ing phase) it is really important to adjust your mentality to that of being a millionaire.
Because, if we don't we will lose all of our crypto millions.
Being rich isn't about fancy cars and fast houses, it is about a mindset of always having enough money. Buying what is important, and buying good quality.
The Millionaire Next Door is probably a bit better than Think and Grow Rich for this.
