This is going to sound slightly harsh, and by no means it’s an invitation to stop thinking or pondering, I think it’s kind of good to be skeptical and think of possible major oversights in the way we live our life, but this kind of hairsplitting wordsmithing is useless, and possibly what is causing this person to neglect that discipline is just a helpful concept. Reading “an embarrassing amount” of self-help books is not a good sign either, but yes, the majority of that crap is just that; crap.
No one can teach you or force you to like exercise, until you do it and like it, then you understand, then you’ll probably fall off the wagon a couple of times, but at least you’ll know that you’re just being lazy, and that’s fine sometimes, but mostly you’ll have to gain experience in fighting laziness tendencies, and it’s probably harder for some people than others depending on many variables I can’t even list.
Biggest factor for people not having discipline (or not wanting to have it, not liking it, etc…) is that they want a quick solution that makes sense, where the answer is that it’s always difficult, you just have to learn to enjoy it and find ways to come to terms with it. Practice more and do it again.
The author is not rebelling against discipline, but really against the self help industry.
