Some companies encourage employees to come up with a learning plan each year. These usually include what, why, and how for each thing you're interested in learning.
What are you planning on learning in 2020 and what resources do you plan to use to do it?
I'm looking forward to learning:
Graphql - a deep(ish) dive
Statistics - brushing up with an intro course
Devops - will finally read Project Phoenix and see where that takes me
