<prompt> Human: Hi,My situation: I have invested some money in a a broadly diversified portfolio. I spend about one or two days per month on investment research.I also have a job that pays quite well but it is quite stressful for 40 to 50 hours a week. At the end of the month I often realize that my investments earned me as much or even more than my monthly salary, but I only invested a fraction of the time into investing.Does it make sense to stop working altogether and only invest? However, would doing twice as much or more research really result in double or more the results?Has anyone here experience with this or maybe even know a study? Do you find that putting more time into investing automatically increases performance?Thank you!  <response>: A rising market makes everybody a genius.Index funds routinely beat people who try to beat the market for a living, so, to answer you question: no, more research doesnt guarantee better results.
