Once you learn the lessons, you can apply them in your life at any age and see the benefits to your happiness and well-being. Low confidence might be holding you back or infecting your relationships or work performance. The joy it brings you spills over into all aspects of your life. Whatever you think you can't handle, you actually can.
Perfection is unattainable, and the pursuit of it makes us boring.
It is our differences, our foibles, and our imperfections that connect us to humanity and make us real.
So much of life is wasted on worry, regret, pain, and heartache.
Of course, some of this is inevitable and necessary. I suppose “life lessons” are called that for a reason.
