Because we often don’t ‘want’ to do what we know we’d actually ‘like’. For example, your instincts or intuitions tell you exercise is bad for you, yet conscious rationality tells you it’s good. The way I ‘hack’ my mind to circumvent this affective interference, is to prime myself. By that I mean, I think about exercise differently. If I tell myself I need to go to the gym, I don’t want to go. If I tell myself I want to go meditate, then I’m filled with motivation to go. I trick my mind by focusing on the aspect of exercise I enjoy most, which is the pleasure I get from deep breathing and meditating through each exercise routine.
