Ask HN: How do you, as a developer, set measurable and actionable goals?

I see a lot of people from other industries, say designers or sales people, who can set for themselves actionable and measurable goals such as "Make one illustration a day", "Make a logo a day" or "Sell X units of Y product a day", "Make X ammount of dollars seeling product Z by date X", etc.

How do you, as a developer, set measurable goals for yourself, being it at work or in your side hobbie?
