Hey guys, I have battled with discipline/willpower issues my entire life, and I'm finally getting fucking tired of it, but still failing often.

How do I actually get better at this shit? I assume monk mode is a good answer, and if that really is the only/best way, how do I do this while still in a cohabitating LTR?

Any actual practical advice is much appreciated. Even half-measures would be good at this point, it would seem.
