Do something!!! It all starts with one little step. Decide what you want to be, then be that person. Want to be a gardener? Plant one type of flowers and sell them in big, lush bunches at the local farmers' market this summer. Want to be a writer? Start a blog and write minimum one paragraph, then press the publish button minimum three times weekly. It is free after all and what do you have to lose?
My mantra is "Do what is possible, not what is perfect". Some of the most talented people I know never do anything because they are waiting until they achieve perfection in their field. Sadly, this means many talented people never get started. This leaves the field wide open for people like you and me who are willing to take a few risks and look a little bit silly.
I love Jennifer Lopez's get "On the Floor" (and do something :), when I need to inspire myself to take the next step. The ladies who work for me say J. Lo is not actually singing about starting a business or anything of the sort, but it gets me moving!
My second bit of advice is to remember that no matter how big your dreams are (and big dreams is my middle name), there is always something bigger. Remembering this brings peace to my heart and puts the world in perspective. I may do something big, but at the end of the day, it is not my responsibility to save the world. Takes a little pressure off which gives me the courage I need to take baby steps.
Oh, and please leave a comment when you discover what your songs are!
