I will be making $55-$60/h by the time I’m certified at 21/22.I am also looking into side hustles to increase my income such as flipping cars, reselling etc.As of right now I have around 8k saved, and 5k invested in stocks.Obviously I cannot buy a property with just a few grand right now, but basically I just want to ask for any advice or tips you would give to me or your younger self when you started.I usually listen to audio books on personal finance and business while working instead of music to further my knowledge.Any sort of advice is welcome, books, podcasts, methods to learn about.
