Talk about motivation #1 Let's talk about some basic concept about motivation in my opinion. First, willpower (which mainly determine motivation) is like physical strength. Once you do any work out, you consume your energy from your body. That means if you use too much willpower to do something in the morning, you would have less willpower in the evening. As a result, it would be harder to do anything that needs willpower. For example, you probably wouldn't feel good enough to do exercise after you finished you work that cost you much energy. Therefore, if you want to do something that is hard or not feeling motivated to do, you better schedule that activity at the time you have enough willpower (for me, it's morning). That implied anything that cost you willpower would affect your performance later. Resisting to eat the tasty cake might make me harder to write an article on here, so I better don't let myself see any tasty cake before I write this :). However, suitable amount of exercise would be good for your body, so is to willpower. Doing nothing needs willpower might lead to lack of it. It's complicated to decide what should I do or what shouldn't sometimes.
