Preparation and foundation building are what makes life flow easier. And you can apply this to fitness or anything. I will give examples related to health and fitness bc that is my lane.

A clean and organized space makes it easier to grab your shoes and keys and get out for a run or to the gym. You don’t spend a bunch of extra time searching for things and you can get to the mission at hand.
Organized drawers, free of ill fitting or holey clothes, makes it easy to grab and go without much contemplation. Saving time helps get started with the mission.
Buying nice stuff that fits and getting rid of old stuff on a regular basis helps you look nice, feel good, and save time Bc you should know your possessions.

Keeping staples like: onion, garlic, olive oil, butter, flour, sugar, and the like make meal planning simply a motion of filling in the missing pieces of your meal.

Kitchen gadgets can be clutch. Having to chop and stew and defrost stuff takes time. Many ppl don’t have time. Kitchen gadgets are an investment that can simply save time and energy. And help you get on to the mission…of eating!!

Keep control of your schedule. Creating time constraints and keeping to it creates pressure. And sometimes pressure is what some ppl need. If I need to do something by 9am, that means my workout, shower, and refueling needs to be done by 8:30. It means I need to be out of the bed by 7am. It means I need to be in bed at a reasonable time with my clothes laid out and workout plan created. This makes my morning routine flow. And with enough practice, creating a morning and bed time routine becomes second nature.
Habits create a lifestyle. How I eat, dress, organize, move, and create is second nature. It can be applied to anything that you want to be second nature as well.
