6 Things I Wish I'd Known 20 Years Ago

I've been working for more than 20 years, and sometimes I wish I could go back to my younger self and share some hard-won wisdom. How lovely it would be to whisper in my young ear the knowledge that would save a lot of mistakes, tears and frustration. The only problem is, I wouldn't have any of that knowledge without years on the job and life experience spent regularly, sometimes spectacularly, failing. I had to mess up and age in order to learn the lessons in the first place.
