Hahahaha.... its okay. a lot of writers and musicians try a genre and realize that isnt their forte. Good for you for discovering that it wasn't what came naturally to you. People will take the word failure the wrong way. But i think its a powerful tool. For example if I can't write a country song to save my life or the ones i wrote were terrible, then that's a good tool to have. Self recognition is great. It will save you from years of frustration by going in a direction that you arent as well equipped to do, dont have a natural knack for, or dare i use the term you used and suck at it. Its okay to suck at something. No one is perfect.
