The reason why I retrospect

Keep doing something, like studying, reading or working, is important because it’s really hard to do something steadily.
But also I think looking back what I did is also important.

Because I can reflect on it through the past. Like I did it but if I tried it in this way, then I could do more efficiently.

And further, it will be a one of indicators for our future.
For instance, studying new technique, designing new architecture or et cetera.

So I think it’s a one of important habit that I have to have and do steadily so that I can manage my own career and skills.
