If you could tell your younger self one thing, what would it be and why?

I want to say to my younger self, “Don’t worry about the future. Everything’s going to be fine.” When I think about my past, sometimes I was worried too much about the future, and yet nothing bad happened. I realized that my future depends on my present. People tend to find their life’s meaning in the future. I think if I can’t find anything like that now, I won’t ever attain that kind of happiness. All I have to do is just to focus on the present and do my best in relation to everything that I try to do.
