I learned this almost 3 years ago, when my dog died. All the walks I postponed, all the playing time I was too lazy to do, and so on.

Now with my other dog it doesn't matter how tired I am. I always wake up at the same hour, no matter when I went to sleep, and take him out to play or to a walk. I cherish every second. Every silent moment, every thing he breaks, every bad behavior (which I of course correct or don't encourage), every minute he wants to sleep with me, I enjoy everything. Whenever he does something silly or just plain bad I'll just laugh and call him an asshole (in a caring way). I'm now unable to not enjoy anything he does.

My late dog, Tomi, left me with a valuable lesson when he died. I thank him and miss him every fucking day.
