Inspirational people part 1

Today I've came across a video where Will Smith was talking about motivation.
I knew he was a good actor, and I've appreciated him as an artist, however I didn't know that he was so motivated and could serves as a great source of inspiration.
Here are some of his thoughts that I find especially insightful and in line with my outlook on life:

"There's a delusional idea that all successful people have- they believe what others don't believe.  They believe that something different can happen."
"If you believe in your goal there's no need for a plan B- coz' it only distracts you from the plan A."
"Excel yourself everyday. Act as a maniac on a mission.  If you want to be good at something you must possess skill. You learn the skill by working hard everyday, by making an effort and trying to be better day by day."
"Being realistic is the most commonly travelled road ro mediocrity."

The last quote is my favourite. You must believe in yourself and your dreams no matter what. Dreams are not realistic, and only great people achieve what's beyond other reach.
Let's our dreams soar, and never doubt in yourself.
