I think my WANT came a few years ago. I was in a 4 year relationship and was functioning very poorly. I was actively psychotic 90% of the day. I was completely dependent on my partner for almost everything.
It got to be too much for him to take. So he ended our relationship. I had to move out on my own for the first time in my life.
That experience made me WANT to get better ASAP. I vowed that I would never be that dependent on anyone again.
I started pushing myself. And I actually started to get better.
Now my ex partner is my friend, and part of my support network. Along with a few other friends, they’ve motivated me to keep fighting to improve.
And I keep them in mind every day as I try to improve. It definitely gives me a continuous sense of WANT 
Blessings,
