Alternativ was to organize my thoughts in a personal notebook or trust my amazing memory to never fail.
I would use this blog as my life journal to organise the different bits and pieces of my learnings and experiences, over the years, which form my philosophy of different aspects of life on earth & beyond (including but not restricted to the subjects of Personal Finance, Investing, Behaviorial Economics, Psychology etc.).
I am confident that by putting this out for everyone, to comment and critic, would help me reinforce or replace the weak or defective chunks in my philosophy.
