It's a nice post, with a lot of valuable insights. There is one that I disagree with though: "Never abandon the root node".
There are plenty of instances that show that in reality this is not what happens, and in fact this is often a necessary step of reinventing yourself if things really aren't working for you. The mid-life crisis is a famous example of this, or even the quarter-life crisis. In some specific psychological circles this is referred to as "disintegration". Sometimes carefully backtracking is simply not enough, and growth needs this kind large shock to the system.
