I have no porblem with abstract thinking.
I have problems ... not only thinking linearly...
physically navigating in a linear fashion.
Just the opposite.
For example - one thing -
I'll pour a cup of coffee.
Go to open a packet of sweetner ...
dump the sweetner in the trash -
and drop the empty packets in my coffee.
I've done that so many times now -
I've practically quit using sweetner.
