Having a hard time building self-discipline?
Commit to building discipline first.
Join a class, enroll in a course, get a coach, etc., where you’re simply told what to do and you can focus on getting really damn good at doing what you’re told—regardless of how much you don’t want to do whatever that is (in a constructive, healthy, held-accountable way).
Do your research, of course, and don’t settle until you come to an arrangement that’s aligned with your personality type and preferences; one that’s with a person or a group you respect.
Once you do (and this is the key), make the conscious choice to replace the words that come from your ego with the words that come from this new source. In other words, don’t let your inner voice talk you out of doing what you’re told to do.
Because it’s that inner voice—your ego—that’s precisely the problem.
The path is this: discipline leads to self-discipline which leads to habits.
Flex the “do-it-even-when-you-don’t-want-to-do-it” muscle enough and eventually, it’ll be strong enough for you to flex on your own. Flex it on your own enough and eventually, it’ll become an automatic type of response that your ego slowly stops fighting you over.
This is the way.
P.s. Not sure where to start? Try enrolling in a local martial arts class. The discipline I build in martial arts became the foundation for all of the “automatic” type habits I have in my life.
