You're impossible is different to mine.
Mine has no limit, while yours could be simply getting out of bed.

Take new chances, step beyond the normal, push yourself to strive to be the best that you could ever be; the world will not wait for you. It will not wait for you to make a start, it will keep turning no matter what. 

Do what ever you feel is incredible. Step outside of your comfort zone. Do not be a prey in a planet full of wolves. Do not be another face in the crowd or a quiet voice amongst thousands of others.

Do not just exist.

You're better then that.

No matter how much you do not believe it. Each person is unique, it's time to show the world just how unique you are.
Write your name on the wall next to some of the greatest people alive, put your picture in the hall of fame, put you're star on Hollywood Boulevard and make yourself known.

Life will be over before you know it.
Take as many opportunities to greater your person. Be the best you can be. 

Be the person that no one can demoralise or break. 

Like I said before; Do Not Just Exist.
