I moved to the one place I could do both every day. Surf in the morning, build in the afternoon, overlap with everyone else's working day after that. The order isn't negotiable; the rest is.
Technology
Ten years of product, the last two with my hands on the code. The part I'm for is the one before any of that: finding the real problem under the stated one.
Surfing
Started late, came back to it after a two-year gap, and now surf almost every day. The progression is slow and completely absorbing, which is the point.
They're the same skill. Read what's in front of you, pick a line, commit.
