My dear friend Dr. Rick Wilson, DMD posted an incredibly simple thought that many of us forget.

One helps the short-term and costs a lot, one helps the long-term and costs a little. Choose wisely, grasshopper.
PS Yes, I read a lot of stuff outside of my industry. You should, too. There are some amazing lessons when you go looking for them.
