Motivating yourself, I think having big strong legs, that's pretty cool. Having a big VMOs [the teardrop-shaped muscle above your knee] is always nice. But, the thing is, when you see guys who are clearly gym junkies who only do bicep curls all day every day, and you see them walking down the street. . . 'Mate, what about the legs?'.
Don't be overwhelmed by a man's fancy car, fancy house or fancy clothes. It's really the person inside the care, house and clothes that matters. By the same token, don't be underwhelmed by a less-than-fancy car, house or clohtes. Women can earn the car and house themselves, and you can always buy your man nice clothes, too.
