Procrastination? That's completely foreign to me.

Especially things that may help me or that I really should do to prevent problems I always do at once.

I am never ever so reckless and self-damaging or -depriving.
It's no surprise I jumped at the chance to try DBT treatment.
I did do some research though. Part of it is rather like Buddhist or Stoic teachings.
But I hope in practice it's a bit more "compassionate" than what is typical in what I see as borderline personality treatment, not seeing us as unruly, attention-seeking, oppositional saboteurs who have a completely dysfunctional personality, something we can just change if only we tried.
A personality serves a purpose even if some/much of it is dysfunctional.
