Running when it's hot never feels that appealing, but I've been stoking the fire of my fitness motivation recently, so I slipped on some Sweaty Betty and headed out for a rather sweaty run.
My pace was slow (lots of hills) but actually it felt pretty good. Not much beats a pleasant run in the late evening sunshine.
Motivation doesn't fall on some, but not others. It doesn't exist in a magical powder.
Motivation is created by action - the more you do something, the more motivated you become.
Sometimes you just need to break the inertia and just do.
