You set your mind to getting the task done as quickly and efficiently as possible. Make it a challenge. Challenge yourself then set a reward for yourself upon completion. Don't dwell on the fact you dislike the task. Focus on getting it done realizing there will always be times you'll be asked or forced to do things you dislike.
It's all a state of mind, be determined and set a goal and be strong and of good courage and you will overcome and succeed, a winner never quits and a quitter never wins, you can do it on your own strength but its way better with God the father creator of heaven and earth and lover of your soul.
