12 Life Hacks you can use every single day.

Eat 30 grams of protein for breakfast. Your mind will be able to focus and sustain longer than most (e.g 2 eggs, sliced apple dipped in peanut butter, yogurt with almonds).
Turn the last 30 seconds of your shower cold. Check out cold therapy (its a start).
Take print-screen of key meeting points, ppt slides, website, links, etc. If you really need to remember something write it down in a pocket notebook.
Carry 3.5 in. by 5.5 in. notebook (fits into most pants back-pocket)
If you want to learn a new skill, approach it like you are going to teach it while you study/practice. Outline a minimum list of topics or sub-skills to master. Focus relentlessly on those areas.
Use coconut oil, its weirdly versatile.
Drink Kombucha instead of beer.
Set a 60 minute timer and actually create something (e.g. a meal, blog post, reusable program, draw a picture, plant a small garden). Uninterrupted 60 minutes can be powerful and fulfilling.
Speed up phone charge time with airplane mode and lowest brightness setting.
Make a list of your everyday carry. Alleviates mental load each morning before you leave home.
Use black background on powerpoint presentations. Studies show it comes off more professional.
Introduce yourself first, you will never regret it.
