Nagging Question #1

In my life I have made some really bad decisions, as well as some super good decisions. I set goals when I was younger, just like everyone else does, and I achieved every single one of them by the age of 24. I was married with two awesome kids, made lots of money, was advancing quickly in my career, owned my own home, had the cars I wanted, all the toys my husband wanted and a terrific extended family. Yet I still felt this huge hole in my heart. So I kept filling it up with everything I could buy. Nagging question #1: Why am I still not happy?
