How to give my brain a job to do?

I recently had a situation in my life where my 91 year old mom was in the hospital for stroke like symptoms. She did not have a stroke but had a reaction to too much aspirin from her recent hip surgery. She was in the hospital for five days in a row on two different visits.

From my weekly one on one coaching call I found out that I really gave my brain a job to do (get mom out of hospital healthy) and it really came through for me!  Rarely did I have to model my thoughts; not like “typical” everyday living. However, at the time all of my brain worked for me without knowing what I was doing and I can’t quite figure out how I did it.  My question is “what is the process to follow to give all of my brain a job to do”?  Thank you!
