Build my own blockchain. I enjoy the technology and I want to demonstrate to myself that I know how it works. I will take an existing codebase, tweak it to be my own, and then build a business around it. This process will have me learn all about the blockchain, and how it works, so I become a subject matter expert.
Become a co-coding force with my girlfriend. She is also a coder, but started 3 years prior to when I began. Co-coding in VSCode is a lot of fun, I want to be able to code with her and be highly proficient.
