Best is subjective. You may not always be able to be THE best, but you can always do YOUR best. Sometimes, we don't have the right tools or enough strength to make a very good attempt, but as long as it was your best attempt, then there isn't any reason to feel shame for failure; because your next attempt will be your best.
Flexible is the best trait. If you see Dragonball & your take away is “be ultimate stubborn” ~ that won’t work out. If the take away is “try a different approach” or be flexible, that’ll help. Cuz like, health issues aren’t solved with stubbornness, and.. that hurt to learn.
If you work hard, do what you love, and live to the fullest, you're going to hit your limit. It's a fact of life. You'll train, perfect, and focus on honing your skills, but one day you're going to wake up and realize you've hit the top of what you can do. And then you're going to look around and see who's around, who's on your level. You may be the top of your bracket, you may be the Goku of your story. But eventually someone is going to come along and kick in your sandcastle and show you that there's more. That you haven't crested the mountain, only the first check point. And that moment, and how you respond, is what sets Good from Exceptional. Your going to either learn to rise, to climb to new heights, to build you and your castle bigger and better and stronger than ever before; or you won't and you will stay at that first check point, in the dirt. Dragon Ball is about, among other things, rising to the occasion, to push your limits. To Go Even Further Beyond! Never Give In, Never Give Up. You'll Be The Hero, It Only A Matter Of Time!
I think you were very tired and started thinking bout dragonball. Although if dragonball makes you want to be better then I’m not gonna discourage that at all. Best of luck to ya and will be excited to see your next creation
The power levels of Dragon Ball are dumb. Goku and a few others have become so powerful that new enemies are invented every few years and the dragon balls are no longer important.
