a lot of people like to "dabble" in the different gears rather than just sticking in one certain path. a common ex. is the mind-set of a student.. again. if there is a student that is a failure, he or she, is initially put down because of the low grades. but then they will find a hard time to gather motivation to continue above that success barrier and to achieve their full potential... a common thing to say to friends (that push you to revise) would be "fuck you, I already failed that last test what is the point in trying again..." boom another test comes, baring in mind the student has not done any work to improve themselves, well not enough. of course they would have done some (in most cases) but the point being is that they would have given up quickly regardless. so they fail again, then they say to their friends: "see I revised and I still failed what is the point?" the thing to understand here is that once that minor bit of revision is done people instantly think: "okay that's it let's call it a day". how many times have you done this? you say to yourself, let's start to read this book... after reading 1 chapter or a few pages, you think, hey I played my part let's call it a day there and do the same tomorrow. yet, when you are on the track of apathy you struggle to even repeat the same thing tomorrow because you can't find the motivation.
