Talk to others who share similar interests as you. Individuality is still the name of the game, however. Meet new people when your friends get sick of hearing you talk about your hobby. Join offline support groups and online forums to meet others who enjoy your hobby.
Hiking is a great hobby that helps keep you in shape while enjoying nature. Look for multiple hiking routes near home and start basking in nature's wonders. Find a companion, fill your backpack and hike off to somewhere beautiful for lunch.
