There are always reasons for people's behaviour, and it's easy just to dismiss them and assume that we already know their story, especially if they're no good at showing their emotions. Life gives you all these knocks, it's so easy to form a shell to protect yourself. I've done it myself.
Do not allow to slip away from you freedoms the people who came before you won with such hard knocks.
Too often, the opportunity knocks, but by the time you push back the chain, push back the bolt, unhook the two locks and shut off the burglar alarm, it's too late.
If you want to be an actor, you should just get out there and do it. I don't go for the approach of first getting photos and an agent. I think you should start with the work, and the other stuff will follow. As with 'opportunity knocks,' you have to be ready.
Opportunity knocks only once. You never know if you'll get another opportunity.
