Physical health is the basis of energy, and thus the source of success. Physical health is about weight, fitness and sleep.

Weight is essential because it reduces the effort required to do physical activities, and because it reduces the risk of many diseases.

Weight is “calories in” minus “calories out”. Calories in is dominated by diet with a minor contribution from exercise. A great way to see this is comparing what you eat to physical Activity. A box of French fries adds 400 calories to your day, but running for 30 minutes only burns 300 calories.

I recommend setting a weight goal, and checking that goal is constantly being met. It’s easy for your weight to gradually creep up, and keep creeping up. Thus, I strongly recommend committing to not letting your weight exceed your goal for too long.

Personally, I set a weight pledge every month, and never exceed that weight. Many people feel dieting is shameful. I couldn’t disagree more. Dieting shows you care about health and are doing something about it.

Fitness is essential because it’s the limiting factor to what you can accomplish.

Fitness can be endurance or strength. For the majority of activities, endurance dominates, but some minimal strength is also required. For example, being able to run 30 minutes ensures you won’t be out of breath when you need to hustle to catch the bus, but being able to lift 100lbs doesn’t help you in many situations. Being able to lift 10 lbs is important though, so don’t completely ignore strength.

I recommend doing the most vigorous cardio activity you can comfortably do multiple times a week. It’s easy to skip your activity, so try to set it up so you don’ have excuses to skip.

Personally, I run 4 miles on a tread mill multiple times a week at the gym. I run inside so weather can’t keep me from running, and I keep gym clothes in a locker at the gym so I can’t have the “I forgot my gym shoes” excuse either.

Sleep is essential because it allows your body to heal, your brain to think clearly, and you to perform well throughout the day.

Sleep is a personal thing, with different people requiring different amounts. The amount of sleep you need should be dictated by how tired you feel. I recommend getting as much sleep as you need.

Personally I set an alarm and always wake up at the same, regardless of how tired I am. When I’m not getting enough sleep I actually reduce my caffeine to make sure I’m so tired, I fall asleep early. Many people feel they don’t have enough time for sleep, but I couldn’t disagree more. Not sleeping makes everything worse, resulting in you getting less done. Getting enough sleep show you want to get the most done in your waking hours.

ps. Being a nerd I use a bunch of toys to help with my health.


My health is in the shitter - and I’m doing none of these. How should I start?

First good for you! Realizing you need to take action is a huge first step. Realizing you need to start small and deliberate is the next huge step.

I’d start with cardio exercise (e.g. endurance fitness). That will give you the most energy, which you’ll require to boost strap the other disciplines. After youve been doing that for a month or so, I’d tackle sleep and when that feels stable I’d add weight loss.
