what can i do to better myself physically like what mindset should i have? im 5'8 and a little over weight?

Honestly, this description fits me perfectly, I'm 5'9" and about 180, I have a little bit of a gut, but most of my weight is in my arms and legs, you could say I'm kind of muscular in my arms and legs, but I definitely don't have a six pack of abs... From my experience, if you are nice, can make a girl laugh, and carry yourself with confidence, looks come after that. Guys like to think that girls hold looks most important but from my experience girls love that I am funny, and the fact that I have a little bit of a gut makes them feel better about themselves. The girl I am currently seeing is ripped, she does cross-fit two to three times a week during the summer and is an ocean lifeguard. She says that the fact that I have a little bit of a gut is nice, makes me more comfortable to cuddle and makes her feel confident. I make her laugh, treat her with respect, and we just genuinely enjoy each other's presence...
