"You can do it! And whenever you think you can't, look at the horizon and see for yourself that even the sky has managed to touch the earth.
And never forget that what you see in yourself might not be what ALLAH sees in you.Remember Prophet Musa (PBUH)? He had a speech defect but ALLAH still made him talk to the Pharaoh. If most of us were in this situation, we would've felt very self-conscious and nervous. And maybe Musa (PBUH) felt the same way.
But you see, even if Musa (PBUH) thought like that, ALLAH didn't. ALLAH knew that Musa (PBUH) was perfect for the job because He saw more in him than Musa (PBUH) saw in himself.And the same applies to you and I.
ALLAH sees more in you than you see in yourself.
So, get up and go for it! You can do it!"
