I totally understand. Totally. This is a dangerous path taken, but it could happen for everyday things. Having the inner pressure to do things when things dont need to be done only to avoid feeling stale.

I was better than anyone I knew in my job and I kept studying edge cases of my profession that I would never need. Soon my job became too easy. I would spend time studying professioms related to mine only in case I come up with something useful. Make no mistake this was not workaholism since it had nothing to do with my day to day work except in very rare circumstances. I also know that this is personally unproductive since I work as a manager and I can tell mismanagement of resources I mile away. I am very strict unfortunately only on everybody else but me. I read issue queues and follow forums for open source projects for thing I will never use. Same thing goes for stackoverflow for a series of languages. I have studied history books, correlating things on various books and sources and historical archives. Attempting to put everything in an elasticsearch cluster for better fulltext search. To what end, I don't know. My spouse has gotten used to this but my friends seem to have changed during the years. I have no long term goals and many things I learned I won't use. Since my addictions are not fun related they just look like hobbies. The problem is they add up to many hours a day.

I would not call it rage to succeed, I would call it inability to stand still mentally.
