Just looking for an outlet...

I'm searching for some sort of creative outlet for myself. I feel like once I decide which avenue to follow I can be relatively successful. Remember, this is just for my own personal enrichment/enjoyment. As of this morning, I was thinking I could go one of three ways...

Studio Art (drawing, painting, photography, etc)

This would seem the most likely path for me to take. I have had classes in drawing, painting, 2D design, and art history. Now for the breakdown.

Pros:

• I have some training in Studio Art and will most likely take to this path easily.
• I "doodle" quite a lot when I'm bored.
• I have some of the materials left from my old classes.
• My mother-in-law is a gifted artist and she could give me critiques and pointers on my work.

Cons:

• Most times I feel like I'm not creative enough to come up with original ideas.
• I criticize my work so much that I often don't finish, I just give up.

There's the breakdown, but a lot of the Cons were from when I was in classes and I feel I may be able to overcome some of my personal setbacks.

Writing:

I feel like I have some pretty decent ideas for stories. Not a novel or anything major, but maybe start out with some short stories.

Pros:

• I can do this from my house for the most part.
• I can hopefully get some pointers online.
• I have read a lot of short stories and pretty much know the general set up.
• I could have my sisters read my stuff for pointers/editing. 

Cons:

• I have never in my life written an entire story. Outside of writing assignments for school.
• I don't have any previous training in creative writing.
• What about when I run out of ideas?

Acting/Drama:

Everyone who knows me knows that I'm in love with musical theater. I feel that if I were to get some real training that I could do something worthwhile in acting. I feel I could really do well in theater, I would love to be a completely different person even if just for a little while.

Pros:

• It would give me more incentive to work on my physical appearance.
• I think it could be fun.

Cons:

• I REALLY have no experience or training in acting.
• I occasionally suffer from stage fright, I can usually push through, but again, I don't know how it would work out.
• I don't even know how I would begin to do this. I'm not in school anymore, I don't have access to drama classes etc. It would take some research to find out what my options are.

I don't know exactly which path I'm going to take. Maybe I'll start with one and see if I like it enough to make a go at it. If I don't like one I'll just switch it up.
