I regret everyday that I did not follow my passions, some I did but working with animals has always been one and living in England has been another. Sometimes it's just too late, I will never live in England will visit again but there are such strict laws on immagration and at my age it's impossible but working with animals I can do.
So follow your dreams, don' let any one stop you. It is your life to spend any way in which you choose and there are NO do overs, so grab your dreams and head out to a happy and forfilling life. Best of luck, and enjoy the ride.
