What should i do?

Hi everybody! This is my first post here and i made this track.

I'm 26 years old guy from Finland and i hate to waste my time on things that isn't useful for anyone.

In my teenage years i loved to make electronic music, but after i moved away from my parents to my own apartment i quit making music.

Now after many years i downloaded fruityloops demo and made my first track in ten years. It took me about 20 hours to make this track so i feel like i wasted lot of my time on this although i enjoyed making it.

I want to hear your opinion if i should buy full version of Fruityloops and make another song or just quit it and use my time on something more useful.

Thank you!
