You can't really choose how you look. It's all genetics.
Fortunately, looks fundamentally only have a social aspect, which means it fundamentally only affects how another perceives you.
It doesn't affect anything else, and there are far more things in the human world than the social aspect.
You're still just as smart as you are. You're still just as committed to whatever it is you want to excel at. You're still going to find interest in some things while other things you are not going to be interested in.
You can still ride down a water slide, you can still drive a car, you can still study physics and invent something to change the world, or whatever you want to pursue.
In fact, in many respects, you're lucky. People finding you less attractive means you don't have to worry as much, as much, still have to worry a little, but not as much about someone using and abusing you for what you have in your pants.
I mean the beautiful in this world, they've got nothing. They are the bar that people aspire to take down. So many a worthless compete to obtain the beautiful. They attempt to manipulate the beautiful and hurt them so much in their competition for getting them that the beautiful so that they become integrity-compromised husks of their former lofty goals as kids.
Certainly, the ugly fall into the same problem, often from wanting to feel beautiful, and someone takes advantage of that, but they are far more advantaged in learning to be self-sufficient and happy with themselves instead of with how others think of them.
That wanting to feel beautiful and appreciated is pretty powerful and destroys most of the ugly, but when you find an ugly who is self-sufficient and strong, they're typically more self-sufficient and strong than a beautiful who is self-sufficient and strong.
The reason for this is because the beautiful learned also, but unless they were ugly at one time, they never had to deal with learning how not to care what others think in the same way that an ugly has too. Sometimes they do, especially if they resist allowing themselves to be treated better because they are beautiful, but usually not.
In other words, a beautiful seems far more likely to compromise themselves than an ugly, that is unless the ugly is going through that wanting to feel beautiful and appreciated. Once the ugly gets past that weakness, it's much harder to destroy them outside of their own corruptibility, which we are all subject too regardless of what we look like.
