Too Late, Too committed?

Okay so i swim like five to six times a week already and do this karate class twice a week am i too committed already to start dance class one a week and am i too old to start dance if I'm still in my early high school years if the last time i did it i was like 7?
Should i go with dance or swimming or could i juggle both I don't know which to choose to be more dedicated to..
