Never miss a habit 2 days in a row
The so called 2-day rule says that one should never miss a habit 2 days in a row.
It's said to increase consistency and likelihood of true habit formation. I have tried it for the last 2 months and I have to say, it really increased my consistency a lot.

Name it to tame it
Learned this in Josh Tichauer (new tab)'s blog post The power of empathy in software development leadership (new tab) about emotional intelligence.
He starts by talking about how important emotional intelligence is as a manager and later recommends a technique to develop it.

He recommends the "Name it to tame it" technique to develop emotional intelligence and it's quite simple: You name the emotion you are feeling which helps to regulate the amygdala, the area responsible for processing emotions.
This technique allows you to respond to challenging situations with clarity and compassion, rather than being controlled by your emotions.

I've done it in the past, but for some reason I never really kept up with it: Writing down one thing that you learned each day is a great way to reflect on your day and appreciate what you're doing.
Therefore, I'm starting this little page to remind myself to add those learnings from time to time.
