The grace and gift of growing older is that you start to realize what really matters in life and you have little tolerance for bullsh*t. You speak with conviction about your beliefs.You become more comfortable in your own skin, and there are only minute traces of the insecurities of your adolescence. You are a little bit more fearless - because you've hurdled the aches and pains of young adulthood and you survived. It doesn't mean life gets easier - for there are bigger crossroads along the way - but in a way, it becomes simpler, because you have a firm grasp of your anchors and what's important to you.
Much is to be gained by growing older. The dots of your past start to connect and make sense and life becomes richer.
