Believe in your own Divine nature
Despite the varying religious backgrounds that the world offers, all religions have one thing in common - a belief that their deity ordains each person's existence here on earth, usually through direct assistance in the birth process by the creation and gifting of a soul. That means that you are here because the omnipotent creator of the Universe thinks it's a good idea. And also, it follows by simple logic that if you are here, and alive, then some part of you (your soul or some other version of life force) is literally God-derived and often enough there is a direct and personal interest on the part of the deity in your being alive and doing the work you were sent here to do. How can you possibly fail with a genealogy and support system like that?
Remember your Source, and that you wouldn't be here unless you were supposed to be here. On top of all that, imagine how much spiritual horsepower you must have at your disposal to use, considering the Divine nature of the life force that's running your engine! It's a monument to the ability of the human psyche to generate artificial and self-imposed limitations that you manage to fail at anything!
