I have not only heard that phrase but used it many many times myself. I used to think I understood what that meant but I feel that only today, after hearing an incredibly powerful and inspiring talk by Tony Robbins (yes I know many of you have very mixed feelings about him but there is something to it!) that my friend sent me (http://tinyurl.com/l8z5oe) do I truly understand the meaning of that phrase. My key take away was this: With every experience in life there are three questions to ask yourself, 1) What do I choose to focus on? (e.g. is it a new beginning or an ending?) 2) What meaning will I give it? (positive or negative?) 3) What will I choose to do about it? (e.g. my own action vs. waiting for someone else to take action). Now this seems quite simplistic at first, but honestly it is amazing if you try it just once.
