In his book “driven to distraction at work”, the author talks about c-state versus f-state.

C-state

Collected

Curious
Courteous
Caring
Consistent
Concentrated

F-state

Fearful
Fatigued
Feeble
Frantic
Forgetful
Feckless
Flakey
Fucked up

He gives his advice to achieve C-state, acquiring f-state is natural behaviour of ours.

1. Having healthy snacks.
2. A quick burst of exercise( for brain break)
3. Meditate or power nap
4. Vitamin connect(connecting with dear ones, talking with them)
5. Humor(Indulging in watching some shows)
6. Medication(If it is really necessary)
7. Experiment

I believe in some of these mentioned points. What about you?
