There are always countless reasons to drop a practice.
A bad day. The shouting with your partner the night before. Laziness. Your boss just drops trivial tasks on your desk. Friends never call. That asshole just cut me off. Nobody is ever interested in what I do. It is always raining and the weather is crap. After all, why should it matter?
And so on.
I have dropped more practices than I care to admit myself. Until I realised, few years ago, that practices are not about perfection, good weather, healthy relationships, and praises from strangers.
Practices are about habit.
Practices are about commitment.
Practices are about doing.
And if you do long enough, you still get all of the above (and some more) and it does not matter.
