Things you might need to know:

• all open source maintainers (including me!) owe you nothing
• there's some things that good engineers do
• you should stop mentoring first-time contributors to open source projects
• if you're automating things remember that robots are better at pedantry and humans at empathy
• you should have a system to get things done (or you can copy mine)
• you should contribute to open source every friday (or, even better, every weekday)
