If you are always choosing to do somethings with the idea that if it doesn't work out you can always leave then you are living life & your relationships with 'your back door open'. How much of that is really working out for you?
What if you were to do something different and instead choose everything you do with total commitment. What do you think would change if you were to be truly committed to your life? You would have more ease, joy, magic, awareness, possibilities ...... and you would notice that everything and everyone would choose commitment to you too. You would be able to create your life & your relationships beyond what you thought was possible.
