Exactly.
All the small things that I do around my room keeps everything organized and clean. The one tissue that is thrown in a corner or an empty bottle might not seem like a lot, but once I put them in the right place, the difference is quite noticeable. The same applies to my work - at times cleaning a surface or bringing an extra item into the kitchen doesn't seem like a lot, until I do one of those things and I see the difference.
Details matter, in organization, work, happiness, and a lot of other areas. We just have to train ourselves to focus on and pay attention to them.
