Now playing projects has its own standards 1: Do you need me to track every day? If so, don't play 2: Do I need to worry about team tearing and hacker attacks? If so, don't play 3: Do you need me to keep up and scan various data every day? If so, don't play 4: Do I need to care about its life and death every day? If so, don't play I have limited knowledge, bad luck, slow speed, and low ability, so if the project is within my understanding range, I don't have to worry every day and it runs steadily. I understand it at a glance, so I'll go play with it. Starting from this standard, I currently have very few activities to play. I can go out for a run with peace of mind, and when the sun sets, I have the mood to watch the burning clouds.
