What is your learning strategy?

Interesting Question - Link
Some answers worth noticing

1. Unless you are working on that tech stack actively, you cannot remember it all
2. Learn fundamentals. Learn only things based on YOUR needs
3. Interviews aren’t totally reflective of the job but one‘s got to pass the interview before getting to the job.
4. Demonstrate competency of core concepts, get the job, and then rise to the occasion as fast as possible
5. Start building the things that you want to build, and you'll learn what you need to along the way.
6. By deliberately selecting your objectives and evaluating possible solutions based on those objectives.
7. Build stuff. Pick out ideas and just build them to build them
8. As a human, you can't be good at everything. You always need to balance between being average in a lot of topics and good in a few topics.
9. Think of a side project you would enjoy that includes a handful of these technologies and start building it. 

My Approach - Every problem these days requires dusting previous memories, read up minimally to recollect paste efforts, spend time connecting the dots and applying to the context 

Happy Learning!!!
