Ask HN: What are the changes you made in your life and never look back?

I'm interested to hear what are the changes fellow HNers made in their life and never look back again. It could be anything.

For me:

* Inkjet Printer => LaserJet Printer

* PC => Mac

* Monthly Gym Membership => Home Gym

* Sitting all day => Standing Desk

* Shall-not-be-named-sucky-cloud-storage => DropBox
