I just have heaps of them

20. Some formulas…
X projects/yr x 40 years = ?
5 projects/yr x 40 years = 200
25 projects/yr x 40 years = 1000
1000 projects x ½hr/wk = 500hr/wk
There are only 168 hrs in a week

21. OSS projects don’t scale
but neither does raising
pets nor children

22. A dog trainer
having a pet dog vs maintaining many dogs

having a pet project vs maintaining many projects

25. What to maintain?
pet projects and libraries you need each day
