... and save your brainpower for your most important things.
Use checklists, reminders, and automation to get things done without conscious effort.

• Take care of yourself. Your productivity levels depend on it:
• Get enough sleep. Don't sacrifice sleep for work.
• Eat right. Stop eating junk. Exercise.
• Take recovery time.
• Pay attention to your relationships.

• You can have too many important things. If a thing is important, start the day with it.
• Pick measurable behaviors that drive important results. Then, keep records so you have a full picture of your progress.

Block uninterrupted time to work for the important things, remove distractions and don't multitask.

And do that for other people too.
This will bring greater benefits in the long term than spending time concentrating on your weaknesses.
