One of the best questions to ask before investing energy in something is is it worth it?
When you're annoyed about something you can't change - is it worth it? Is it worth investing all that energy in being angry? In impatience? In frustration and annoyance?
There are many things that it is worth getting angry about, but the little things? Let them go.
Choose instead to invest in kindness, generosity, gentleness, patience - the attitudes that will bear worthy fruit.
