Here is a video I recorded the other week of one of our walks. We've walked along this path at least a thousand times. https://www.youtube.com/watch?v=iH4TsjD97cU
Get a dog. Give it all the love you have. You will receive the same, unconditionally. Go do all kinds of things that your little friend enjoys. Go for long walks as often as you can, morning and night, at least. Your friend's excitement and joy over the smallest things will rub off on you too. And you'll come to realize that, to your dog, you are literally everything. It really puts things into perspective. There really isn't much more to life than that, and I think there's a certain beauty to it.
