All your life you are told the things you can not do.

 All your life they will tell you you are not good enough or not strong enough- just not enough. 

They will say you are the wrong person or have the wrong weight or wear the wrong clothes to play this or do this. 

The will tell you "No".

 A thousand times "No". 

Until all the no's bcome meaningless. 

All your life they will tell you "No". 

Quite firmly and very quickly.

They will thell you a "No" and you will give them a "Yes".
