I would say do both! (If it's affordable for your family, and you can manage them with school and other stuff.) BOth of them are really challenging, and I mean it. Ballet may seem easy peesy but it's not.
If you're doing it right, it will be hard. Gymnastics is hard no matter what. If: You like sweat, and pain, and a lot of soreness, with the promise of amazing skills, and looking forward to getting more awesome skills.
Gymnastics. If: You love music, and moving around, and being perfect. Ballet.
They do tend to coincide with each other though. You dance in beam and floor in gymnastics. A lot of acro skills will help your ballet.
I like gymnastics better, but you're not me, so... HOpe I helped!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
