To achieve success in anything in life requires perseverance. As the saying goes, "The race is not for the swift nor the battle for the strong, but for those who endure to the end."
Many have started out with great vigor and expectations for success but never continue, because they were not willing to do what was required until success came. It would be good to listen to the words of Bayard Taylor who said, "Those who would attain to any marked degree of excellence in a chosen pursuit must work, and work hard for it, prince or peasant."
My encouragement to you is to find out what God wants you to do always and work at it through the power of God until it is accomplished.
