As per Maria Konnikova, motivation is required to keep something remember for a long time. I completely agree with her (however I'll call it as interest). We remember a complete movie, all talks happened on coffee table in canteen, and many things but we easily forget what mummy asked us to buy from the market, what subject we studied in last semester of graduation (not even the name of the subject) and many things.
If I talk about myself, whenever some problem comes up on my site, I easily fix it because I remember all the paths of file system, where what file is located. I even remember all important pieces of code. However, if the same thing happens in my office, I take 1-2 days to fix it because I need to contact many people to understand the file system, to know where I can find logs, what are the credentials for log in.
Everyday, I create some diagrams, write some documentation, read the code to keep all the thing in the mind. So can confidently face, understand, and explain any thing from the project.
What should I do to motivate myself to improve my understanding in office work?
