There wasn't anything difficult I did today. I'm still half-headed from a long vacation and wanted to start off easy. Which leaves me wondering about what we're missing to miss out all the relevant bugs that just take a bit of patience to look for.
The testing I did today did not require much testing skill, but it required patience. It required me to try things that are somewhat similar but still different in some dimensions. I need to work on training patience to my fellow developers. Find motivating for that somewhat hard, as it seems our business has survived long enough without it - you could always, so far, fix the problem when someone complains about it within a day. The hard part is to find out the problems are there and leaving the hard parts for others - product managers, customers or maybe a tester - feels so tempting.
