We'll never know until we try...

I have a dream...
But all the people laugh to me...
And they said 'hey...are u serious...?'
and the other said ' hey...that's impossible!!'
they can't stop laughing...

And then they said :
' think once again...you're nothing'
'it's impossible for you...u'r dream is so unreachable'...

And then i answer 'let me try first...we'll never know untill we try '
