Hmm that's a very good question.. I think many, if not all of us have expended and endured a lot of emotional effort in order to get to where we are.. but presumably it has been worth it? Or presumably we have at least been able to get through it, or are working our way through it.
As for me.. on paper I have had a very, very difficult life, been through many things that would destroy some... and it's not like things are perfect and hunky dory now - but I am still here, still smiling and I feel blessed in many ways :)
