Sandy, work out, dress right, make it part of your habit and routine. I like working out because it pumps up my testosterone, which at my age especially is critical (I'm 34). If I don't work out, my sex drive isn't what it used to be and my sexual motivation can flag. When I work out, I'm young again. But then don't get stuck in your head about needing awesome looks... if your mind is occupied with a sense of "I'm not good looking enough yet" every time you see a girl, it will totally fuck you up and become a self-fulfilling prophecy of inaction and zero results. Not good either.
Looks and style are very important in my humble opinion. If you meet a really hot confident girl who spends time and money on her appearance. She is definitely not going to date a guy who makes no effort with his style or appearance. I mean why would she want to walk down the road hand in hand with a scruffy unshaven bloke ?.
