26th Musing: A Small Resolution

Another post about acting! It'll be short (though knowing me it will tangent into something long), I promise!
So as I was giving up on my acting dreams and wondering whether they were truly dreams or something I just thought I wanted to do, I realized that I didn't want to give up just yet.
The thing about me is, I know how to act and what I should do in my mind, but in front of people and expressing it, I suddenly feel awkward in my own body and I feel silly if I use emotion, as if I will actually emote wrong (because, like I said in another post, I'm not good with that). Typical commercials would be so easy for me because it really requires a bright personality and confidence in front of a camera. It's like modeling, but saying a conversation...right?
The real acting lies in complex emotional works. Personally, I prefer tragedies. Some comedies I like, but they don't move me like tragedies do unless done in a certain way that appeals to me personally. I especially do not like musicals like "Grease", "Hairspray", "Fame", etc. I did like the "Hairspray" movie though, that was good, but generally, they're unappealing.
So as I was watching "Thor", I was so inspired by everyone there, especially Tom Hiddleston and so much in the end! His voice, his body language, the depth and emotion he conveyed (especially as he was totally different from how he acts in interviews!!). He's just so brilliant and inspiring, so I would really love to be like him!
Therefore, my resolution is not to give up on acting and put myself into it and any emotions I have. I may not work up to expressing myself in real life, but at least I can do it on stage/camera, whichever (though I feel 50 times more comfortable with the second). I would really like a commercial agent, so I could sort of work up, I guess. The theatre around me is all either musicals or comedies, so my heart wouldn't be in it at all. Is that the wrong attitude?
I suppose we'll see what happens. I have the determination, initiative, and technically the experience, so...who knows?
