You have to do everything that you feel like, but without forcing it. It's good to make mistakes. In Flamenco dance, everything has been done. Thirty years ago they did amazing things and nothing happened, Flamenco is still there. The people are afraid of everything.
Time gives and takes away.
It's very comfortable to stick with one idea all your life. To stay in the past is comfort, not purity. Flamenco is a live art form, that continues to evolve. I think it's one of the most alive cultures that exist. It's not necessary, although some people feel that it is.
