In my case it wasn't that they were hard to do, it was more that I just didn't have the motivation to do them. The change needed was to actually have a reason to start doing any of them. For me, that started with being honest with myself. Deep down inside I knew the reason for my depression, I "just" had to be honest about it to be able to take control over it. Once I did that I gained some motivation to do those things on that list, and so I started doing them. And slowly but surely I got out of my hole. Every now and then I notice I'm halfway back down a hole. I stopped doing those things. Again I have to be honest with myself about why, and with that I can start the climb back out, starting exercising again, eating better etc.
