I have three columns so far:
My philosophy is, there are three layers of things we read/think/talk everyday: information, knowledge and theorem. Information, like news is not meaningful by feeding you info in pieces. Knowledge is little better, it is condensed information summarized by human beings. Theorem is the truth established by means of accepted truths which could guide us as general principal.
I would like to spend more time reading good articles inspiring theorem and great knowledge, rather than dragging by all kinds of news.
Also, when you spend x hours having inputs, make sure you spend x hours to digest and streamline, then x/2 hours to share and provide the output.
(以铜为鉴，可以正衣冠；以人为鉴，可以明得失；以史为鉴，可以知兴替) Bronze-made mirror contributes to setting one’s dressing right, and predecessor-set mirror benefits understanding gain and loss.
Financial product knowledge I learn + some good startups and business ideas I found.
