If I’m starting from zero, what would you suggest me to do?

I just started working and only earns enough to cover my monthly expenses and maybe a little to buy something for myself that I always wanted as a kid but I have big dreams and I honestly don't know where to ask.

Slowly I'll transition to better paying jobs and I want to have my own yt channel I always wanted, want to own a business for my wife in future and build a decent home for my mom and I want to start it now, to invest wisely and not follow any trends so I need help on those who learned it thru life and still going on and where to start and everything for a kid who started his life just now and wants to build a life for himself.
