Productivity

For me it was a very simple rule: If a task takes less than 5 minutes to do, no matter at work or in the household, do it right away. Thinking about when to do it, remembering to do it and having it linger over your head while you're procrastinating takes so much more time than just do the small tasks right away. It's a real boost for efficiency and being productive. See those small things as tiny stones on your way to the goal and you quickly kick them out of the way instead of standing in front of them and thinking about when to kick them.

"Don't do what you love, love everything you do"

All about perspective. You only live once, take care and put your soul into even the most menial tasks.

Using a calendar effectively. Let's say I have a doctor appointment, I put it in my calendar and later update it according to results I get, attach related documents etc. I use Google calendar + drive for this.
