i'm in medical school, i still have 2 more years. but i've also always liked music and singing and performing. i sing, write songs, and play guitar, i have been doing so since i was about 11. i live near some cafes and coffee shops that have people who play live music. what would you think of a young girl who plays music in a cafe on her free time? lame, cute, cool, weird?
I think it's great! If it's something you enjoy, by all means keep it up! I don't know of anyone who would think it was weird or have a negative opinion about it, and if they did, it would be their problem and not yours.
