Interval Mindset Part 2 (?): Patience

Cat 4 Questions is back! I think it would be really interesting to hear about your and other peoples mental approach for difficult workouts and races.  For workouts: what is your optimal level of arousal / excitement?  self talk or in-the moment mindful ness?  what is your emotional perception of the sensations (pain and suffering?  discomfort?  associating exercise discomfort with positive things?)  And I guess similar for races + how do you keep keep things under wrap until it is time to unleash hell?
