Belief

You must believe in your self. Anything short of this, makes success an opponent. Could be you are diligent and positively orientated or an aspiring achiever.

If results are yet to be favourable perhaps you lack one ingredient  - self belief. Perhaps your friends performed a feat by cultivating a plantation in the desert and is making a fortune due to the patronage of desert merchants. Then, you can equally plant there, no matter hostility of the weather. Just belief you can do it.
