I'll start.

Execution
Do what you say you're going to do. Commit to your tasks, and goals. It's that simple.
Take time to rest.
Videogames can be work, but they can also be relaxing, it depends on the game, and they can also be used to break up monotonous tasks.

Exercise and Sleep
For better sleep find a way to release more energy.
Sport, calisthenics, walking, working on posture, even meditation.

Lay in Bed and be Bored
Ideas come to you while you let your mind rest, relax.

Be more Productive at Work
Learn the skills that make you useful, and spend the rest of your time being useful to yourself.

Women
They need you more than you need them. Improve yourself and they will come.

This mean NOFAP motherfuckers
It's not just a placebo, avoid (((their))) porn induced indoctrination

Read
Keep the mind sharp. Your internal discourse is as good as the book you are reading. Know why you're reading and be mindful when you read. Train your mind in the classic texts.

None of this matters if you don't have a scope and tie it all together
Mind and body. Make it an efficient symbiotic relationship, efficiency is after all the German way. Physiology counts, you are a holistic creature not a set of insulated parts.

This means planning for the future and acting it out in the present.
You are limited, choose carefully what you will do and why you are doing it.

Feel good about yourself
Self-improvement is mostly about attitude.

Avoid sugar and junk food
Remember eating good really just means eating regular foods

Prepare food when you are not hungry
So when you are hungry it is available.

Be Social
Find like minded people, good discussion forces your mind to stay in shape by actively listening and constructing arguments that have meaning by exploring your own ideas while you formulate them to another person
