"Shoot for the moon, even if you miss you will land among the stars."

Rough interpretation, dream big.

The first and foremost important step is to unleash all the limitations you have put on your thoughts. If you can't even dare to think outside the box, how do you ever expect to achieve something great? The only limit that exists is the one you have put on yourself; with Allah nothing is impossible.

"For those who believe and are conscious of Allah, For them there is the good news in the worldly life and in the Hereafter." (10:63-64)
