>Maybe, I need to learn to tune everything else out and focus more.

I spend every day practicing, and completely failing at this art. I've come to accept that I cannot ignore things that are going on around me. I cannot choose to focus on something.

I've only being on this planet 25 years, that's not a hell of allot of time, but in this area I can say I have experience. If you want to focus, change your environment. You cannot learn to tune something out. At least, I know I can't.
