I really liked your all points but the attractive is fourth one because once you calculated the profit you could make on your investment plus how much risk you might have to bear. All other problems and factors solved by themselves like the time to book profit and which mindset should one have before booking profit. These all points are useful when one is doing holding instead of trading.

Because I as a holder if follow all these rules (instead If i want to add some more rules) then I will be more than OK.

But still as you said, we all have different mindset and different life hurdle like one could bear the market's bearish cycle but other might not. This current dip has refreshed the memory or fact that we should remain calm and not always so optimistic about something because as life is so unpredictable market is also.
