People with knowledge please guide me.

This is suppose to be a question with people who has experience in the crypto field. I kind of understand how cryptocurrencies work and of course how volatile it is. I want to get into it but I don’t know where to start specially if you are starting with nothing( zero fiats). May I know how would you start and if you are going to start from the beginning specially. I know crypto is not a shortcut to be rich but I would like to future proof myself, retire early and be financially independent at 40. What would be your advises please.
