Do you play only the premium hands or are there exceptions?

I wrote this stuff on another post but I wanted to ask everyone if they only play premium starting hands or if they have exceptions. Some of my biggest hands came when I was the big blind and no one raised me.
When I first started playing I only played the premium hands, like AA23, AAKK or AK23. But I found that I wasn’t playing many hands at all, so I got a little looser and looser and next thing I know I’m chasing after hands all over the place. What makes it much worse is when I fold top set because to board has paired or three connected cards come and see someone take high with two pair! Then it makes me call things I shouldn’t because I think I’m playing with idiots.

Do you strictly play only the premium starting hands or are there exceptions?
