It is great to have goals and want to improve. Being accepting of incomplete change and process is better. Personally, I like the photos that provide inspiration and some written direction for easily improving a situation that could be similar to mine.

Only accepting perfection tends to drain motivation. It also presumes a lot about ability, uses, values, and resources. It also drives wedges between people.

"I hate ugly monoculture yards" is not an helpful for changing minds as "i love native grass yards. Even a few accent areas are great." I fail at this all of the time. It is important that I get it right some of the time.

As for perfectionism creating poor mental models, the results tend to be fragile. If one must be perfect and able all of the time, it will fail. The models tend to not allow for different abilities, resources, or desires.

I hope this was clear. Cheers
