Stumbling blocks or stepping stones?

“It’s a comforting thought that nobody can put stumbling blocks in my way, because I’m learning how to use them to step on as I progress to a saner way of living.” (ODAT, 3 July)

Every apparent difficulty contains a lesson. The questions to ask: What character defects is this activating? What are the opposing virtues to practice? Once I start practising the opposing virtue, the difficulty is retrospectively reclassified as an opportunity.
