But what if I fail?

So what. Why can't you try again?

I might not get the chance.

There'll always be another chance.

But what if?

Do you want this?

I think so.

Then you have to believe you'll get it. Otherwise how will you even try.

So many other people would be better than me. Why would they chose me?

Why not you? Maybe there's something special about you, and you're just blind to it.

And what if they're blind to it also?

Then is it really there?

That's not too encouraging. 

Encourage yourself.

You are myself.

Suck to suck. It's time.
