Something the hematology nurse said to me after I failed my first venepuncture this week:
“To get good at taking bloods, your job is to get through your first 50 fails as fast as possible. Celebrate your wins, sure. But only after you’ve failed 50 times will you finally begin to get good at it.”

Just one of those many examples where quantity beats quality.
