I was just wondering how some of you deal with the mirror psychology. Let me explain – I have been working out for about four months now and when I go to the gym I get a really nice pump. My arms look big for a few hours, but a few hours later they look skinnier than ever, especially during my days off (weekends). How can one stay motivated when the mirror is telling you that your growth is marginal, and if you are having a bad day, you may conclude that you have not advanced one inch. Do bodybuilders (amateurs and professionals) deal with sort of issue?
