Silicon Valley is backwards in this regard. There's this mentality of always being busy; I can't help but feel it is a ruse for extroverts to flash their social proof at each other. In Silicon Valley, people always want to seem busier than they actually are, and people who are not busy are seen as inferior.

The next time someone asks if you're working on a side project, say "no". Carefully notice how their interest quickly turns into contempt. Similarly, people don't want to hear that you're "taking it easy" or "doing nothing" this weekend. That's literally all I tell people at work, and it just turns people off.
