Should I start figure  skating?

Sure. You're not getting any younger, so do it now.

No, it is a waste of time.......

I started skating at 14, only went once a week and right now I can do all single jumps and most spins (not the layback spin). Its such a great sport that has changed my life and I am sure you would enjoy it. If you haven't already started, go for it, its never too late to start! Just try your best and be patient!

Just don't have another incident reminiscent of the Nancy Kerrigan/Tonya Harding incident where Tonya sent a hitman to cap the knees of Kerrigan that led to the end of Nancy Kerrigan's figure skating career.

You can start and see if it is something you'd like to continue doing to get better. If not, at least you tried it.

if you don't start how will you ever find out if you are good at it or just mediochre
