+How to choose a programming language/paradigm to write with.
+
+- programming is about making the program do what you want it to do.
+- not much told, lot harder, and not as natural/intuitive; a program should not
+  do something you do not want it to do.
+
+
+- programming paradigms, functional is superior because it better fit all
+  real-life scenarios.
+- in Machine Learning, Kolmogorov complexity. Object Oriented is worse than
+  Functional programming to represent naturally many real life problems.
+
+What did I learned? Is it a set of specific knowledges or can we discover great
+common principles?
+
+- restart from zero, tabula rasa, what is programming?
+  #+end_comment
+
+I could talk to much about that.
+But a few short written down lessons.
+
+If you want to reach productivity and not necessarily enlightenment.
+You have to stop learning and use what you know well.
+And do not try to use things you don't know.
+
+In particular, most programming languages/ide/workflow/utils/tools have basic
+and advanced features.
+If want want to produce and deliver in time. Your best bet is to limit yourselve to
+a minimal set of features that give you enough power of combination instead of
+looking for a super generic strong solution.
+
+Clojure for example has:
+
+- functions
+- higher-level functions
+- destructuring
+- defmethods
+- protocols
+- macros
+- atoms, agents, core.async
+- Java FFI
+
+In fact, writing a fully working app you only need, basic data structure (edn) and functions.
+
+That's it.
+
+I was part of a team that created an advanced full featured app using only those.
+No magic, just taking care of the state and not writting spaggethi code.
+
+* How I choose
+  - Functional programming is superior to imperative and object oriented
+    languages
