This is something I drew during training a few months ago (I forgot I had this photo):
This was something the teacher taught us about work, but I think it is true for life in general. There are some things we can control, there are some things we can influence (but cannot control), and there are a lot of things we cannot control or influence. If we get upset by things we cannot control or influence, who’s fault is it? If we don’t get upset by things we cannot control or influence, do we not gain a more peaceful mind?
P.S. The kanji below were just practice for the Heisig method. I often do that at work when I am bored. ;p
