Out of those four pillars of the circle of competence, I believe my weakest point is technology, while I'm good at the three other ones. That weakness is what kept me away from the crypto world till a month ago. People usually don't know what they don't know, and I was one of them on this. But I watched a video by cryptobobby suggesting a goal of reading one whitepaper a day for 2018. I've been trying to do that but still it's challenging since big parts of white paper use jargon that non-tech people are not familiar with. I won't give up though and will still work on my weakness till I have a full control on my circle of competence.
