Have you ever gave up something just because you were afraid you might give up on it in the future or not even tried for the same exact reason ?
Well...I realized i haven't really done anything, haven't really experienced anything for the exact same reason and it needs to change.
this quote from the movie "stuck in love" opened my eyes :

"A writer is the sum of their experiences ... go get some."

And I guess the fear of giving up is completely wrong since everything has an ending whether it lasts a longtime or a short time.. it will eventually end.
So go out there! Do what ever you want to do right now ! If you haven't lost your love for it yet then it's gonna make you happy!

Go and live a life you can write about passionately !
