It is pretty hard to keep up with everything but something that always helps me in the mission is the Savior's example. When he had just finished a super hard task of the atonement he did not go take a rest or say that his work was done. He went and just kept working. So whenever I feel just wasted or hurt or whatever I just think that he did not give up so I will not either. It helps alot.I have been enjoying church so much more in the mission because I have spiritual problems that I am looking for answers. The revelation a lot of the times comes from sacrament meeting for me. So just search for those questiones and answers and you can have a much better experience in church to be honest.
