I've written several blogs on the topic of joy—and on the idea of keeping a positive rather than a negative attitude. I know how much better I feel when I see the glass half-full and when I keep a grateful and joyful heart.
It's important to say here, however, that I also firmly believe in being with whatever is real and true for you in your life at the time. If you find yourself in a bad place because of life events or because of depression or for any other reason, it's not helpful to stuff those feelings down and try to put on a happy face. At that point, accepting where you're really at is more honest and authentic. And in the end, that will get you where you need to go. Sometimes the idea of faking it until you make it doesn't work.
I have spent time in those dark places, those wilderness sites, before. That's the time to reach out for help. It's not the time to act as though everything's cool. It's definitely not. Do what you need to do to address the issues before you. And do what you need to do so you feel better. But don't simply put your mask back on and go on as though you're just fine when you're really not. It's OK to feel the way you do. It really is. And it's more than OK to ask for help. From friends, family, a counselor or a coach. Get the help you need—and perhaps the glass will be half-full once again.
