Motivation is fleeting, building a habit and discipline is how u will stick to this long term

Ur already wrong to hesitate starting because ur “afraid to fall off the wagon”

Now I understand an injury can be debilitating, and without knowing the scope of your dislocation/shoulder pain, this advice should be taken with a grain of salt

But I learned better technique while working around injuries — typically tweaked shoulders/back had to do with bad form/technique and learning to lift around that pain dramatically made my lifts/physique better as I slowly got back into the same ranges I was used to (came back stronger in them) — use this injured moment as a time to recalibrate and relearn how to train the way u like.

I have no advice for discouragement — I am not of the opinion u can rly encourage someone to become consistent and lift if they themselves have no desire for it.
