It's not necessarily easier through hobbies, and it's a mistake to think that you want to find someone who's exactly like you.
When you're a couple, you're a team, and you'll need each person's strengths to make it through challenges and offset the other person's flaws.
My girlfriend is more mentally stable and more down to earth than me, and I'm more sensitive and going all over the place mentally. So she can bring me back down to earth when I start to overthink things and I can help her to see things in a different light. She keeps things very simple, in boxes so to speak, which is exactly what I need.
I hope it makes sense. I'm currently meeting a lot of girls because I'm trying to form a new band and many female singers are interested. I could immediately notice that I had a lot in common with them. Of course if you're passionate about music, you have to be sensitive, open-minded and to be able to think out of the box. If I got into a relationship with a girl like that, it'd probably be very intense but we'd start to drift very fast.
I was dating this make-up artist a few years ago, just like me, she was oversensitive and passionate about art. God I had a lot of hope for that relationship, she was geeky too, we used to play video games together and she had a huge collection of retro games and consoles.
There was one problem though, she was basically me when it came to her personality. It always sounds great on paper though but you end up reinforcing your common flaws more than anything else. She'd start crying and then I'd start crying (haha pussy!), she'd start becoming anxious for no reason which then made me more anxious, etc. Plus you get bored very fast because you can't really surprise each other.
Of course you still need to be similar in some aspects, but you don't want someone that's too much like you. You want someone you can contend with, someone who somehow always remains challenging.
I always had so much fun on my dates. The excitement of discovering a person you don't know anything about, hearing their stories, their struggles, relate to them while having fun, and 40% of the time (at least for me) there was the possibility of heavy make-out sessions and sex.
If you're not having fun on dates and find them stressful, I think that's also because of your mindset, or because you've had a string of bad experiences, I don't know. Being on a date was pretty much like having a drink with a friend to me. I never spent much either, most of the time, the girl would insist to pay for her drink anyway.
Of course, I got my fair share of frustrations too, but it's like anything in life, it can't go well all the time. The possibility of failure and disappointment is actually what makes dates exciting.
