Concentration and perseverance
Don’t spread yourself too thin.
If you work on something, you should not spread yourself too thin. One good change in a month is enough if it is well-done, and 10 are worthless if they’re badly executed. Changing habits is something difficult that requires concentration and a lot of work. No more than 2 to 3 changes should be implemented per month, and you should think and only start with something new when you’re sure that you will pull through.
It remains true that if you have a lot of time, you should schedule your work, whereas when you are stressed, you should just go with the flow because you’ll put in enough work automatically.
Ivy league schools and universities vs. lifelong learning
As far as Ivy league schools go, I am of course jealous because I want to be in an enriching environment like these people are. At the same time, I know that there are things in life to be learnt that cannot be taught at school, and my independence and relative level of savvy make me feel quite alright as to my own abilities, but I need more rigor and regularity in my work and studies. But lifelong learning is better than 6 concentrated years of work at some university or school. Lots of tiny steps are stronger, far stronger, than one single effort.
