How do people stay motivated to work out?

Anonymous
I've tried so many times for a few years to get in shape but I can't stay motivated to keep at it. This last time I gave up after a few weeks. I'm not overweight, I'm actually underweight. I eat A LOT! I just can't gain weight, it's a genetic thing, everyone on my mothers side were this way until they were in their 30's or 40's. I'm 5'5'' and weigh 90 lbs. I've been this way for a long time, I have super long legs and arms and it makes me skinnier than I already am. I can't wear skinny jeans as they make me look like I have alien legs. My doctor says my weight is not an issue as long as I'm healthy, which I am. Rarely sick. But do you guys know of anything I can do to help gain weight and stay motivated to work out?
