This might sound weird, but I prefer to do certain things with people and I hate doing them alone.

for example : two of my hobbies, motorcycling and snowboarding. Both are way more fun with one more person, and alright with a group of people, but I just lose motivation to do either by myself.

I had made a plan to go snowboarding recently and I've had people flake left and right, thus making me lazier for wanting to go alone. It's not bad doing it alone, I just feel like I'm depending on people to go out and do it more- and I don't want to do that.

How do I stop? How do I accept doing things with just myself and not relying on others?
