GM! Some advice that I would give to my younger self is to start investing/building as soon as possible. You don't need a lot of money to start off, just consistency and ideas.
Find a niche that you know very well, something that you have spent hundreds of hours on, something that you are passionate about, and scale that idea, that investment, that business as much as you can!
Don't pay too much attention to what other people have to say if they are not on a higher level than you. Most people will not understand what you are trying to do or will try to keep you down at their level.
Fail, but always get back up. You might fail, and people will say, "I told you so," but that's good. You are still one step ahead of them as they most likely never tried anything risky outside their bubble. From failure, you will learn more than from winning. Pain will define you more, and success will test your character.
It's easier to make money than to keep it. Don't wait! Think, plan, act. And of course I would tell my younger self to buy more #Bitcoin.
Much love.
