Here is the first:
You cannot think yourself into a life. You cannot feel your way into a life. You need to get moving with your hands, feet, and mouth. Whenever your mind serves you well on this road - and sometimes it does - listen to it and do what it says. However, if listening keeps you stuck, then it’s time to take stock: allow some gentle space between what your mind says works and matters and what your experience says works and matters. Then recommit to go forward with action because this is the only thing that matters. Mindful acceptance will help you gain the needed space to do just that.
