I have spent too much time and energy making myself feel inadequate and somehow lacking, and I know too many people who are great people, who are well-loved people, who also feel inadequate and somehow lacking. And it makes me sad and angry and frustrated... and absolutely determined to find a way to stop the madness.
Just because you spent the entirety of your 20s focusing upon one or several of the things on your "having it all" list doesn't mean you failed. But, to gain it all, you need to reassess where you are with each item on your list. Is it time to refocus your energy from one item to another? Can you take a break from something to build up another area of your life?
