Jealousy comes from counting others' blessings instead of our own. So very true, don't let your life pass by while you worry about someone else, count your blessings, be grateful, be happy for others (even though it can be hard).
"Someday everything will all make perfect sense, so for now, laugh at the confusion smile through the tears, and keep reminding yourself that everything happens for a reason." Remember this when you are a little lost. Everything happens for a reason.
