I try to focus on values which in my opinion make me a better person. Striving to make sure that the one who went to bed is a better person than the one who woke up. Some of those values are:

* transparency (say how it is, even if it hurts);

* happiness;

* learning / self-improvement (kick yourself out of the comfort zone);

* wellbeing (you can't product the best work if your mind or body are not feeling well);

* servitude (helping others provides more happiness than helping yourself);

* gratitude (to appreciate what you have);

* minimalism / frugality (focus on what is important).
