When you hear an idea that sparks a connection, that taps into a Source for the expression of the idea, then you have been given a clue. The idea may be expressed differently in you; it may be expressed one way one week and another the next.
For instance; let's take exercise. We all know we "should" because it's good for us, but clearly we "should" not all run if we hate it. Finding what has JOY (read more about joy) will increase our chance of success with the idea, goal, action, intention, etc.
What plucks at your heart strings when you think of doing it? If you're doing something with dread, we need to talk. Life is too short not to connect to our passions...and how will our children learn to connect to theirs?
