What Is the Most Valuable Thing You Can Learn in One Hour?
For me in 2019, it is learning to get started to write and just write.<p>Ideas to long form content that is fully developed, fully formed and fully proofchecked content is an extremely laborious process.<p>PG had a tweet out once ... just write ... publish or not publish is secondary. (something like that). I tried to implement and do that now.<p>Just beginning to write can be learned easily in an hour and the return on effort is, IMHO, fantastic. It can commercially be pretty useful but the mental clarity  itself makes it worth it.<p>The second is meditation ... read The Mind Illuminated ... just the first stage (the author lays out a lot of progressive experience). Jump straight to the first stage chapter and just do it and repeat! I don't even try to progress further in practice ... it's pretty tough! The first stage is itself worth it.
