Can thinking "positive" change the outcome of things?

For example, if I think positive about getting into my top university, will it happen? Of course I have good grades & put in a lot of effort into the application, but it is very competitive and sometimes I feel like I don’t have a chance. But some people say, if I think "positive," I will get in. Is this true? What’s your experience with thinking positive?

Attitude is almost everything. What it lacks, effort will make up for. You already have the physical part down (good grades), so when you combine that with a good positive attitude you will be unstoppable.

Best wishes for you in being sucessful at your top university. Post some pics after you get in. :)
