I am in favor of really BIG, AUDACIOUS goals. You should definitely want to achieve them and know why your goals are important to you. This gives you a solid foundation from which to excel.
That said, I truly believe that the actions you decide to take to move you toward your goals should be absolutely doable. The actual size will depend on where you start. Bottom line is that you can execute any action with the talents, time, and motivation you have at the moment. If you can’t, then make the step smaller and smaller and smaller if that’s what it takes.
Set up yourself to win again and again and again. Then all of your “within reach” steps will accelerate your growth, success, and happiness.
Enjoy your day.
