Yesterday I wrote about the technique you can try to train yourself to overcome perfectionism. Let's try it with another example.
Imagine that you are trying to build the “perfect” essay today. Following the exercise, replace “perfect” with a different quality. You haven't written for a long time, so you decide to make this essay at least 200 words long. You are free to write whatever you want and for any amount of time, you just need to write 200+ words. This is possible and proven to work by this community. Setting a quality like this works, and you will definitely achieve this result.
However, when it comes down to more difficult projects, picking just one quality will not work. Imagine that you are a plane designer, so you want to create a perfect plane. Replace “perfect” with fastest, and you are in a big trouble. If you will build the fastest plane — it will not likely be very safe for passenger travel and you will not be able to sell it. The same to the safest plane if you decided to build one. The safest plane is the one that doesn't fly...
In larger projects that can't be completed in a day or a week, you can't ignore everything except one thing. There needs to be the balance of different ingredients, similar to cooking. That's why this exercise is not applicable to large projects. But training yourself to keep in mind only what is important is something that can help you solve the perfectionism problem.
