And, as the great and very intelligent William Shakespeare wrote, "THIS ABOVE ALL--to thine own self be true."
I have tried to live by this for years and I cannot count the times it has helped me to make a decision I would have otherwise struggled with. You are the only one who is with you your whole life so you need to do what works for YOU.
And the real meaning to me is the first part of the quote: This above all. So true!
