You know that feeling when every thing seems easy and right? When you don't have to struggle to find passion for your work, when your instincts rise clearly and you are able to take action without debate and doubt? That feeling that all things are possible? I have a friend that calls that "The Blue Place".
Don't we all want to be in the blue place? 
I find that for me the blue place is a reward for taking care of what is important. First on that list is my health and mental state. I can chase the blue place like a mad woman, but if I am under slept or under nourished, I will never find it. If my desk is untidy, and my filing incomplete, the illusive blue space will skip away. I prize my positive mental state far too much to allow for it to slip away when a little timely attention to details can make all the difference.
To court my blue place I do take care of myself, I eat right and make proper sleep a priority. I take care of tiny details like a tidy office before they become an issue. If this is constant struggle for you I suggest you read any of Stephen Covey's books, such as The Seven Habits of Highly Effective People. After reading Stephen Covey you will never be bogged down by inconsequential tasks again.
More important than anything else, I take the time to feed my brain positive information. The more positive I am the more often I find myself in my own blue space. Being positive, thinking and feeling positive, feeding positive input into your brain, is a commitment that you make for yourself. If you make the commitment it will reward your life in untold ways. Give it a try.
Coco,
Funny that your friend would describe a "happy" place as the Blue place:) So now, if I am feeling blue, it's a good thing! I totally agree with putting positive input into ourselves. It really does work!
