From The 30 second habit with a lifelong impact by Robyn Scott:

If you only do one thing, do this: Immediately after every lecture, meeting, or any significant experience, take 30 seconds — no more, no less — to write down the most important points.

I’ve been trying it out for a few months. Here’s what I’ve found so far:
– It’s not note taking
– It’s hard work
– Detail is a trap
– You must act quickly
– You learn to listen better, and ask better questions
– You’re able to help others more
– It gets easier and more valuable

Life is fast and it teaches us a lot of things. It always helps to jot down the lessons learned so that you can re-visit them and shorten your learning curve. In turn, you will make less mistakes.

Also, writing down your notes in a notebook is another habit to look towards. This is something from which we are moving away from in the digital age. But, it seems it has some value, value which might get lost in the fast moving pace of life. Taking notes manually helps concentrate our minds better and get the best out of note taking.
