Your personal journey through life will eventually get you where you need to go, regardless of how much you worry.
We burden our selves with ridiculously high expectations daily. When we fail to meet those expectations we stress out and start to worry.
While a little bit of pressure helps keep us motivated, too much pressure is self defeating.
Life is good when you have goals, but life is even BETTER when you can find happiness in the journey towards those goals.
So lighten up, be happy, and enjoy the ride!
