The more general a piece of advice is, the more amount of people can associate with it in more situations. Once you get into more details, it is easier to apply to a specific situation of a certain person. That is why these short sentences of advice can only be really used as motivation or inspiration to search for more reliable and good help, to apply them would do more harm than good in my opinion.
What you're saying is pretty interesting, because I think we all classified people in different categories when we were children, and as we evolved those categories evolved too. To answer your questions:
My classifications seem to be way too complex to explain, not even I understand them, but to put it simply, I think I classify between people who I get on well with and people who I don't get on well with. After that, it becomes a dichotomous classification and it just branches out. It's after that first classification that I see whether they have their shit together or not and what kind of person they are. What I dislike about my first classification, is that when I'm not sure if I get on with this person or not, I get confused and frustrated and I don't really know what to think of them.
Yes, definitely. They change categories and that becomes pretty confusing too. If they do, I normally tell myself that actually they were always in that category and I just wasn't able to grasp that. It's kind of rare that they change, but I had a friend with whom I had a fight and after that we never talked again. I guess it's simply because I had not realised 'who they really were'.
That is a good question, and one I could not answer. I think you will never stop understanding the models, because as you said, they are always changing. To be honest, I would say what is next is to start acting upon them. Once you understand a model, try applying it to real life. For example, imagine you classify a certain person as 'advanced'. Try applying what they do to your life, and experiment around to see if you perceive yourself as getting closer to this 'advanced' section.
It's just a suggestion, but I think it's a very interesting topic!
Having a constant clean workspace helps me. I always use a lot papers and files, so I've learnt that cleaning up a bit every hour or so really helps.
I think the best place would be in a quiet small coffee shop with not too many people where you have a nice big table to yourself in a corner and with the lovely smell of coffee and buns... so beautiful haha
At the moment my workspace is the library, because my desk at home is tiny and makes it hard to concentrate. But cleaning up the current workspace will definitely make it easier to get to work tomorrow for me.
Hahahha I love your last approach.
I must say, what works best for me is simply removing said cookie. I never eat junk food. Why? Because I don't have any. I never watch television. Why? Because I don't have one. (Might seem extreme but I can't have one anyway because I live in a shared flat and we have no place to put one, I just watch tv shows on my laptop)
Another strategy is the reward system. Did you spend less than 30 minutes watching tv today? Here you go, buy yourself a cookie. Sometimes this work, sometimes it doesn't. The best is to just keep trying different approaches and you will eventually find the one that works.
