I believe it was Thomas Jefferson that said "Never put off until tomorrow, what you can do today", which is such a great quote when it comes to health and fitness. When you think about it, so many of our unaccomplished dreams are delayed due to procrastination or not feeling "ready" to take on someting. I think a better quote is this:
"If we wait until we are ready, we'll be waiting for the rest of our lives"
I mean, when are you really every 100% fully READY for something new? When it comes to health and fitness every single minute can make a difference. So if you were waiting to hit the gym until you felt like you had more time, or you were going to start eating healthier after your birthday celebration, or you were waiting for take that new fitness class until lost 5 more pounds, DON'T! "Just do it" as Nike says and you will figure it out along the way.
