Motivation

I think I've read a few things about motivation but I am still looking hard inside myself to maintain it. Motivation is a great concept when you have a plan and you are working through it, but high expectations or any expectations that are not met during your measurement of work accomplished can throw you off. I am thrown off. I know how much work I have done and the results let me know that I need to work harder. What most people are finding to be easy, I am finding it to be rather difficult. I am not complaining but I have been in small crying spells for the last two months. I have moments of doubt and even when I work on my personal development, I have failed to follow through with my plans. I am very upset about my behavior, but I am not giving up.
