I think it's very simple process to get rich with ASX shares.
Some people try to make it complicated, but I think you could say it just boils down to: spending less than you earn, investing it and then being patient.
Obviously there are many variations within each of those aspects, but I think most of the money matters you can deal with are related to one of those aspects.
Spending less than you earn is obvious for everyone to understand. Money comes and money goes out. If more money goes out than comes in you're going to have a bad financial life and you could end up in a negative financial spiral of trying to pay off high interest credit cards.
Everyone's finances are different, so there's no one-size-fits-all approach. If you're a low earner then somehow you need to boost your income, perhaps with a side hustle or a few hours of a second job. If you're a big earner then it is more a matter of reducing expenses without reducing your happiness.
There are many free resources you could use to track your spending such as Zip Co Ltd's (ASX: Z1P) Pocketbook.
The next step is just to start investing it. There's no 'wrong' way to invest, just try to minimise your brokerage costs and choose investments you think have solid profit growth potential, not simply one that is the flavour of the month or year.
For a set-and-forget type investment I'd be happy to choose things like MFF Capital Investments Ltd (ASX: MFF), iShares S&P 500 ETF (ASX: IVV) and Washington H. Soul Pattinson and Co. Ltd (ASX: SOL).
The final step is being patient. People describe paint drying as a boring process, which really doesn't take long compared to the amount of time you need to leave good investments for compounding. It takes years for shares to grow properly.
