I do not think there is much difference.
I believe thinking is a register/reaction
and feeling is simply a reaction of higher intensity
(even becoming a prolonged willfull action
{note: will is not always conscious}).
I would rather limit my reactions
from what I would consider motivational distractions
(I need no motivation when I have programming that can not be ignored).
Think about how many distracting reactions are related to addiction/habit
(fill in the blank_____________________________________________________

and how many are related to withdrawl/restlessness,
such as tapping fingers, bouncing knees, biting lips, scratching iches, etc.
I do not need to care.
I do not live for pleasure.
I live to get things done.
