How to I feel passionate about the activities that interest me?

Dancing and drawing always interested me. But these days I feel resistance when I try to do it. It's like, whenever there's a picture that pops in my mind and when I try to execute it in a drawing book, I just fail in it. I end up drawing some crap and then close it. Same with dance. I picture some steps in my mind and again fail to execute it. This is my everyday routine. I do feel passionate about dancing and drawing but I don't know what is that I am lacking, that brings failure in it. Sometimes, I doubt whether I am enough passionate about it. How can bring back the fire of passion for these activities back into my life?
Thanks

Why is dying alone considered to be such a bad fate........?

In the society we live in, if a man never asks a woman out people will he will die alone. Why is that such a bad thing? Relationships aren't for everyone. I don't ask women out and I don't expect them to ask me out. To be honest, I just don't care at all. I've had women interested in me but I didn't care at all. I don't know why but I just don't. Maybe I'm sort of selfish who knows. I do have friends though. So what if a guy doesn't ask a woman out in his lifetime. Why is dying alone without a spouse such a bad fate? We all die alone....

Harder because you have to worry about bills, work and family.

I guess if you have a good job then it's easier because you enjoy what you do but it's alot harder being an adult than a child or a teenager.

Feeling like the third wheel lately. What should I do?

My best friend is a boy & he usually asks me to hang out with him & his girl. We sometimes go drinking in his house or we go to the park or to some other places ect. He met this girl like 3 in a half months ago. I didn't think that they'd still be together for this long, especially since he's the player type. I'm really starting to feel that I shouldn't always be hanging out with them all the time. It feels so awkward at times because my friend grabs his girl & starts kissing her in front of me. I'm glad he's happy & that he's doing his thing, but I just rather not be around if I'm going to feel like the third wheel. Me & my friend have another close friend, but he rarely hangs out with me, my best friend, & his girl. My friend's girlfriend is really cool & street smart. Me & her get along so well & we share a lot in common, since we have the same ethnicity background. Its funny because that's when my friend feels left out. Me & my friend are both Hispanic, but instead he doesn't know Spanish, but kind of understands it. I really respect that I have a friend that doesn't act all like he forgot all his closest friends just because he has a girl friend, but I feel so weird being the third-wheel. I kind of feel like telling him that I don't feel comfortable being around them all the time unless an extra person is being with us. I feel like they need their space even though they want to be around me, but I need to limit myself. What should I do?

I essentially have everything going for me
Looks(not to sound into myself), I'm young 20, am in an amazing relationship, making ok money, lots to look forward too...
But I just can't seem to relax and be happy.
I am self conscious of everything I do and say. And my body.
It is really hard.

What should I do?
