Ask HN: What activities are worth doing while working on a startup?

So, being fairly recent to Silicon Valley myself, I would say without a doubt, start-up reading is insanely helpful. I'd start with some of the books with lots of amazing start-up lessons like the Lean Startup and read blogs from other entrepreneurs and notable VCs (Paul Graham, Bothsidesofthetable, AVC, et al). Hacker News is also a pretty great community to search for help on stuff as it comes up.

Beyond doing lots of reading, I'd say, it depends. The start-up mantra is, build something people want. If you find writing/blogging can help you on that path, do it. Certainly meeting and talking to lots of potential customers is a must. Building a product is also a must. I think about the choices of what I'm doing and always try to filter it by whether or not it will get me closer to these things.

But it will really depend on your business. I'd personally recommend finding certain things to relax you that you invest some time in, whether it be meditation or exercise etc. Other than that, try to focus your energy on the next best thing that will get you closer to customers.
