Iím jealous that my best friend gets to travel. How to cope with this?

My best friend for 10 years has constantly been traveling around Latin America. He usually goes backpacking or even joining some meet Latin tours just for the fun of it. Needless to say, he sure does have a lot of time and money to spend and Iím honestly jealous. I miss hanging out with him, I guess. But still, I donít know how to deal with this negative feeling and I donít ever want to think about opening this up with him. Can someone help me sort myself out or give me some advice to feel happier with my life?
