- have experience of creating commonly used features, say profiling slow apps, drag & drop, etc.
- do experiments & gain exposure on things
- doing this will make things easier when you'll have to implement a similar functionality
2. 👀 keep an eye on ecosystem
- technology moves fast, & you must too
- don't get stuck in "work stack"
- have a pulse of what's new in tech, know what to dig in & what to ignore
- focus on why to use a new tool, rather than use it for hype
