Persevere. There are times when things have to be done and you truly are the only one who can do them. Sometimes, this involves tasks you may not want to do. But you persevere in order to move forward. Perseverance gets things done.
Keep going. You know that chipping away at it will bring it to completion. This period is temporary. Better activities will follow. But for now, just keep at it.
Keep a positive attitude about your task. You have the power to choose your response to situations. Choose an attitude of perseverance. Remember, perseverance builds character. It has to be done. Get it done and move on to other things.
