Working out tips?

Ok.. So I started working out recently.. I want to build muscle and lose a little bit of weight. But that's not my main concern. I'm happy with my weight really but I want to be physically more fit. So I worked out today and I know it'll be a process and results aren't immediate. However I was wondering if anyone had some tips? And also kind of a random question but for squats.. How many is a good amount? I did 50 today..
