What Advice Would You Give Yourself If You Could Go Back In Time?

I saw this picture today, and I ask myself this question all the time (and I love DBZ if you haven't read my other posts). I really don't know what I would personally tell a younger me, if anything. Changing one thing in my past could completely change who I am today, for better or worse.

But, if I had to pick something to tell a younger me, I would say the following: take more risks, go one more adventures, say yes to more opportunities, don't be scared. This is something I learned to live by at an older age, but I feel like I could have had a lot of unique experiences if I harnessed this earlier. What about you? Comment your thoughts, I'm genuinely curious.
