A few simple rules everyone should be doing: Don't spend more than you earn, save or invest the difference, avoid debt.
That is pretty much the only rule you need to follow to be rich. It does not really matter how much you earn. If you spend more than you earn, then you will never be rich. If you save some and try to implement you will sooner or latter see results.
Also, you need very little to be happy.
And be careful, cuz new property creates new costs: Taxes for cars and houses. Room for shoes and clothes. Electricity for smartphones and TVs. And so on.
This is where the brilliant BTC comes in. You buy it and you don't even pay banks or taxes (in theory).
