What about my arms??

I have this stupid obsession : my arms... My husband always tells me : who cares about arms ? And I know he is right but I have also have bigger arms. Whenever I look at myself, that's all I see in tank tops ... my stupid arms. I'm not afraid to put muscles in them but I can't see to get a better definition ... Help ! What do you suggest ? How do you get over your own hang-ups ? Thank you
