One of my favorite quotes is by Goethe, "Whatever you can do, or dream you can, begin it./Boldness has genius, power, and magic in it."
The reason I find it so powerful is that we all have the same amount of hours in a day and yet so many of us sleepwalk through our lives. We say we'll do the things we enjoy some day. And that some day might not ever come. My daughter is a great example of seizing the moment.
In about two weeks, she will be embarking on a trip around the world with my granddaughter who is 7. For almost a year, she methodically planned where they would visit, how long they would stay, some things to see while in these locations and generally realizing that this is an opportunity for her and her daughter to see the world, experience other cultures, and expand their worldview "now" and not in some distant future where time feels short.

I am not saying I have planned every aspect of my life with no room for flexibility, spontaneity or surprise. I am saying that if you don't have a goal, along with an action plan, it's simply day dreaming and wishes, and at the end of your days, you'll be left thinking about what could have been.
I read a book once that talked about the ways in which men and women "go for it" and that women have to "know it all" before they take action. And men understand that you can "learn it all" on the job.
My action step for you today is put your goal on paper. It's easy to dismiss the goal when it's in your head. Putting it on paper, along with a deadline, makes you accountable, at least to yourself.
