It is okay to not be perfect on the first time and need to work on something until it is better! Even in the Christian life we will not reach full perfection or maturity here on earth, but that doesn't mean that we should give up on growing in the knowledge of God and in His ways. Paul, during his first imprisonment in Rome wrote in Philippians 3:12-14, "Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus." Paul was an Apostle, and yet he was not yet perfect! Was he content in that state? No! He pressed on to know Christ more perfectly and to attain the prize. By the end of Paul's life we read, "For I am already being poured out as a drink offering, and the time of my departure has come. I have fought the good fight, I have finished the race, I have kept the faith. Henceforth there is laid up for me the crown of righteousness, which the Lord, the righteous judge, will award to me on that Day, and not only to me but also to all who have loved his appearing." (2 Timothy 4:6-8) Paul had been diligent in serving God, even when it was difficult, and by the end he knew that he would receive the prize.
I encourage you to persevere in all that you do, both the large and the small things, but most importantly in knowing and serving our righteous God! In Him you will find the greatest reward and satisfaction.
"Do you not know that in a race all the runners run, but only one receives the prize? So run that you may obtain it. Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable." 1 Corinthians 9:24-25
