There’s an infinite number of things you can focus on.
It’s important to keep a “clean mind” where everything is ignored except for your most important tasks.
This means you need to say “No” often. The following are things that might be helpful to avoid:
- People who distract you
- Making long term obligations when unnecessary
- Purchasing posessions that are time consuming to manage unless you can easily hire someone to manage them
- Complex and indefinite plans (things need to be kept simple)
- Agreements with unclear upfront expectations
Keeping a clean mind helps you stay agile and reduce stress, so I highly recommend it.
