“The easiest form of reflection, in my opinion, is to keep a journal. Just the act of writing can summon ideas that may not otherwise have surfaced just noodling around in your head. It allows you to dump everything out on paper (or a screen) and then sort it out and make sense of it.
It’s a good idea to do this once a day or once a week for five to ten minutes, or whatever time you have to spare–I’m sure you’ll find the experience beneficial. The idea is to get into a habit so that, for example, every Friday at 2pm you’ll stop and make some notes. The important thing is that you state the situation and what you learned from it. And it’s ‘the what I learned from it’ that’s the important part.” – Take a Look Back at Your 2014 Year With These 5 Questions, Geil Browning
