Stand Tall or Fall?

People tell me that

I should give up

Give in

That my dreams are foolish daydreams

 Fit only for a child

My answer is

No

Let the word ring out

Let strength fill me and banish fear

Let the world see me smile

For though I may be small

I am far from insignficant

Now is the time to stand tall

For life sometimes knocks me down

But I vow to get back up
