Quoted from jellikit:
There is one thing that has kept me in the hobby for nearly 20 years - friends.
For me it all comes down to this.
As an adult, you find, or at least I found, you don't make new friends much. I honestly hadn't made any new friends in probably 10 years, because of the insular life I lived.
That all changed once I got into pinball. All of a sudden I was in this new world of "You like pinball? I like pinball! Why don't you come over to my house, stranger?" .
I play in a weekly league, and the best part of that is usually we meet up for dinner before hand and hang out. That is my favorite part.
There's been plenty of weeks where I just didn't feel like going, but every time I make myself go, I always feel good about it and feel good coming home having had a nice break from things and hanging out with people I enjoy.
