Let's start here: where you start and where you want to go. You can learn from the past, but the present is what matters, and what we do today and every day can shape what the future will be like for us.
Every day there are new variables, and variables that do not change.
Our lives are a very complex system, which is why there are no laws or solutions that work for everyone. But there are more objective principles and variables, inherent in people and in reality. Some have remained valid for centuries; others arise from and belong to the era and present in which we live. They have been explored by great people and minds from the past and our time.
We need to be good at bringing in our own parameters, our own variables, and getting to know as many mental models as possible, in order to understand how they fit and can be shaped and fitted into our lives, so that we can move closer to the right direction every day. We will never hit it exactly, but it exists for each of us, and even if we never do, every day we can move closer to it or further away from it. That depends largely on us.
