Just a thought i've had in general.
People limit themselves, a majority of the world limits them selves to what they can and can't do. You hear constantly "I would love to be able to do that", "I wish I was that good", "I would be rubbish". These are all self set barriers, and why? because people don't want to try, they feel like they are what they are at that exact moment and cannot be more than that. They contain the possibility of what they could be, and what they should be, to saying "oh, I'm not good enough". The age old saying "you don't know until you try" really applies. It is sad to see people are content with doing nothing with their lives because they think they can't do anything big, the people that are successful are people who are willing to go outside their comfort zone and fall over a few times.
What's worse are the negative people, the people who are too scared to try anything so who ever does try, they call an "idiot". So that in their head they feel above someone because they are too weak in them selves to open their mind. People are capable of amazing things, name a million successful and amazing people.. they are PEOPLE not freaks.
Anyway, yeah :) Just a thought
