•Staying in present. Philosophers called it 'optimal state of consciousness', Psychologists call it Flow, Rich kids call it as Mindfulness. What ever it's called, its just simple focus on the present and it works wonders on mental health.
•Using DND/Aeroplane mode more i.e. limiting phone calls to absolutely when needed. As a side-effect saves battery as well & good for privacy too.
•Using email over chat, improved the quality of communication & again good for privacy too.
IMHO:
-> Mindfulness is "constant emotional self-awareness". It's a skill that enables you to being aware of your emotions and state of mind while experiencing your day to day life. This sounds ridiculous until you realize that most people aren't aware of how emotions influence their rational decision-making. We can easily see how others become temporary irrational for emotional reasons but somehow we also try to denial that the same happens to us on a regular basis. A mindful person is in a way constantly calling theirself out in their mind (e.g. "I'm currently overenthusiastic/angry/anxious/etc. because of ...")
-> I think of "Flow" as a state of mind. It can be achieved by doing something that creates a positive feedback loop with challenges and achievements. This series of challenges can be of physical/cognitive/etc. nature but needs to be always of the right difficulty level. Too hard tasks will make you feel overwhelmed while easy tasks create boredom. Both extremes will make you lose your focus and/or motivation and that's where mindfulness can be helpful. Once you become aware of the problem, you can adjust the difficulty level by adjusting the difficulty with better goal-setting and other productivity tricks. Hit the sweet spot multiple times in a row and you achieve Flow.
