April showers bring forth May flowers

This is deceptively simple - a statement of an obvious bit of weather lore but look a little deeper and it is telling us that what we may not like can be the cause of something good. Difficult times can and often do lead to better times so we must put up with difficulties and look forward to the good times. Nasty medicines can be the means to better health. Saving can lead to prosperity. Hard work can create the funds for a good holiday. Tears at parting can be the precursor to the joyful sunshine of return.
