Even if we want to achieve things, if we are not ready, and if we have doubts in our hearts and we keep making excuses for things, then it will be hard for that thing to come to pass.
We have to be ready first in our hearts and mind and it will manifest in our actions. We have to believe it first in order to receive it.
"Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours." -Mark 11:24 ESV
