If you learn from your suffering, and really come to understand the lesson you were taught, you might be able to help someone else who's now in the same phase you may have just completed. Maybe that's what it's all about after all.
If you happen to meet a crocodile, don't stick your head in its mouth. Every now and then, and who knows the reason, people ignore this advice, which is sad because they die, but very stupid because they were warned. They had a choice. The moral of the story is this - you can't afford to be stupid. There are crocodiles.
