Here are what I am learning in 2020. I try to be a holistic person. So I am learning technical skills, business skills, and social skills.

Technical: Blockchain programming (mostly on Ethereum). I believe Ethereum is the future. Programmable money. How cool is that?

However if you think blockchain is fad, you could replace it with cybersecurity.

Business: Corporate finance (stocks, bonds, future contracts, options, etc). This is related with blockchain because I believe a lot of financial applications will move to blockchain platform.

However if you think blockchain is fad, corporate finance itself is a useful skill for investment and analyzing company's finance. Just now, I learned that you could make two bonds with different risks and yields into one security which you can divide into senior tranches and junior tranches. It's very interesting.

Social: Negotiation. I am reading Chris Voss' book (Never Split The Difference). He has a class in MasterClass as well. Coursera has a couple of negotiation courses. In the past, I received the shorter end of the stick because I'm not good at negotiation. So I'll try to change that.

Happy acquiring skills!
