You can envision it, work for it, try to control it, pray for it, study for it, pay for it, cry for it, and do your absolute best to have it, but after that, you have to truly just believe and let go of it.
People tend to obsess over things they really want, but there's no use of obsessing and stressing over it,because after you do your best, you did everything you can do.
I published a post a while back about being in control and having thoughts control you, that concept goes hand in hand with what I am saying here.
Believing and being patient is a huge sign of strength and it's one of the biggest actions you can take towards a goal.
Remember this always, it's not stress that kills us, it's our reaction to it.
