Hey, J, gotta watch out for those expectations.....ya know?
My son is an only child. I think it is important not to generalize or feed into stereotypes, dont you?
He is the most selfless, compassionate, kindest, most humble human being I have ever known.
Thats not to say that you being an only child may have contributed to some of your stuff. So dig in there.....
Just have to remember that you dont want to blame anyone for who you are today. That just doesnt serve you well. Gotta own it before you can change it.
