"Do not wait; the time will never be 'just right'. Start where you stand and work with whatever tools you may have at your command, and better tools will be found as you go along." - George Herbert
You will never know what heights you can reach or what dreams can be achieved if you don't try.
Push yourself outside your comfort zone, sign up for a race, try a new sport, learn a new skill, or even begin taking classes toward a degree you've always wanted to have. You can accomplish anything with enough consistency, persistence, and determination.
When you're faced with uncertainty or the feeling that you should quit, keep moving forward. Take the time to learn from what isn't working to take it and turn it into something that will!
What decision will you make today?
