Who is that self? Do you feel as though you're ticking the boxes, doing what you thought you wanted, what you thought you should, the "norm"? I'd guess you're wondering why you aren't entirely happy, given that you have a "good" life and everyone else seems to be doing just fine.
Perhaps you find yourself saying things that leave you with an uneasy feeling in your stomach, things that feel untrue somehow. And have you noticed that the majority of your time seems to be taken up with stuff that, at best, you feel indifferent to and, at worst, you have to force yourself through?
And if you feel anything like I used to, you're probably feeling disconnected from yourself and from your life, often asking yourself "This can't be it surely?"
Deep down you know something has to change, but what would make you happy? And how could you make big changes in your life anyway?
