I've bolded the parts I don't understand. Are you saying that you came up with these ideas yourself? Or is this based on the knowledge or experience of others?
My investment strategy is based in my opinions that were at least partially formed by reading from and listening to professionals. My opinion on the second point you highlighted is based on my belief that "set it and forget it" doesn't have to mean never look at it for 50 years, looking at it again decades down the road should be close enough to set it and forget it to make the increased potential worthwhile.
Keep in mind, I'm still young (under 30) so my outlook has little to no foresight for short to mid term effects, and it's entirely based on the long term.
