It is really hard to beat the indexes consistently and that comes from training.
I am behind education and training, the more I work/research/read/analyze, the better I am. When you work hard, you get paid. This is brainy work, I am very much attached to this like a game, trying to refine the process more and more, read as many as books. Only regret is “why did not I start early?”, esp on systematic methodology … reading books.
If I continue like this, I may be better in next 5 years or far better latter in next 10 years. Then, education and training stays forever with us.
