Why am I a coward?

I just realized that i never do things that i want and i reached a point in my life where i got the impression that i don't want anything!. I get scared doing things like for example turning the air conditioning on when it's too hot because if something happened my dad would blame me or even showing a girl that i like her because she would cheat on me because i'm not that active in life or you could say i don't have the potential attitude for a relationship, or buying new clothes because i always throw my new clothes (i don't like to own things) i'm starting to run out of clothes lol (i also always delete anything on my phone massages, pictures, etc.. you name it). I think all of these behaviors are defining my cowardness, what are your opinions?
