Two important principles of time management

1. Delegate

2. It can wait.

These are also conducive to good mental health.

The second is not a mandate for procrastination.
Rather it is a mandate to be pro-active rather than reactive, to set and stick to priorities, to not let the squeaky wheel get the most oil, to let people solve their own problems,  ....

I often feel pressure to get a long list of things done as soon as possible. This is not good for my stress level and mental health. However, if I can calm down and let things go, and come back to them later, I will have a better sense of perspective.

I don't claim to have the best time management. Some earlier thoughts are here.
