I make my living as an stage actor.
You wouldn't believe the amount of people who look down on me when I tell them. But I love it. I was born for the stage and have always known this. In high school I was involved often with the school's productions, which were hell (in hindsight I can see how unprofessional it was), but I would not change it for the world, because without that I would never be where I am now.
I am fairly successful. The only thing that gets to me is the many, many people who think it is so easy to stand up on stage and present a believable character. You have to be constantly aware of your position on stage and the position of everyone else, as well as how you are projecting your character, where you are in the dialogue, pitch, pace, tone, of the voice etc. etc. It really is a physical and mental workout, and that is why it is fantastic. It is a hobby more than a job, really, and there is nothing better that making a living of something you love.
My heart breaks when I speak to a certain friend of mine. He has worked for eight years in the same dead-end office drudgery, and is just yearning for an escape. It was his dream to be an actor too, but his father died and he needed to support his mother on something more regular, and so took up the job. He so wants to get into the industry, but it is a fickle one, and doesn't want to take risks, so he is stuck.
One of the biggest sins that the world commits is stifling those who really have what it takes to make it. If you want to be an astronaut, go for it, if you want to be a cook, go for it. It doesn't matter who you are or how old you are.
Go for it. Break the mould. Be you own person.
Reach for the stars.
