“Poor Time Management” probably brings up different ideas in different heads. Ideas of schedules and day planners and vision boards etc. But it seems to me that all of those tools aside there’s one ability, and only one, that sets the good time management folks apart from all the others. It’s the ability to ground their schedules in reality.
If you’re going to go on and on with the rest of the hamsters on the cardio equipment AT LEAST switch up the pieces of equipment. Not just between workouts, but within the same workout. So instead of a half hour on the tread mill do ten minutes each on the bike, elliptical machine, and tread mill. This is the bare minimum of variety you should be doing.
