In my whole life, I have known no wise people (over a broad subject matter area) who didn't read all the time — none, zero. You'd be amazed at how much Warren reads — at how much I read. My children laugh at me. They think I'm a book with a couple of legs sticking out

About Myself
I try to live according to the following core values, which I describe in Core Values:
- “Discipline”: Commitment to finish completely everything we start
- “Organization”: Having all resources available at the beginning of everything we start
- “Continuous improvement”: Never-ending improvement of everything we do every day; also known as education or non-complacency
For example, I recently completed a Certificate in Project Management (“discipline”) because I believe in permanent education (“continuous improvement”) and, at the same time, I want to increase my employment opportunities while I attend to a university later on (“organization”)
In addition, I am an independent dreamer who learned to fulfil my goals through detailed planning and execution. I find interesting that some personality tests have confirmed me as a dreamer!
I trend to behave like an INTJ (Introvert, Intuitive, Thinker, Judging) according to the Jung–Myers-Briggs personality topology, which can be find at the following links:
My hobbies are mostly reading, watching movies — specially old ones from Anthony Quinn, Audrey Hepburn, Cary Grant, Sean Connery and Mario Moreno Cantinflas —, walking and riding my bicycle around
I have no sustainable interest in sports or religious matters. However, I have learn about religion and communal interaction because my parents have a strong religious background and they are natural leaders. In the other side, I never appreciated athletics because I used to be short-sighted and a little over-weight, but I recognize that some exercise today will help us to keep medical bills reasonable as we age
Eventually I will do some travel to see other nations because I have an insatiable curiosity for business and how societies organize themselves to accumulate and distribute capital across generations
Portraits
Personal Goals
I have been working professionally in the systems and software and computer science industries for over 15 years and I love it. I want to remain working professionally for another 30 years at least!
I am a middle-aged Software Engineer, and I am planning for a career change sometime during the next 10 years. Nobody really wants to hire a white-hair Software Engineer. We eventually become too grumpy while working with younger people. My old university classmates have mostly moved to Sales, Project Management and Middle Managerial positions, but these areas provide not better long-term employment prospects for the same reasons: technology progress makes our work either obsolete or easier every day, and younger professionals are cheaper
Technology knowledge is not accumulative: everything we learn in technology becomes obsolete soon and we must start over again. Even though this is a prime characteristic of capitalism, this creative destruction is not present in other areas of expertise like capital allocation and finance. Investment and insurance gurus like Warren Buffett and Charlie Munger remain working actively in their 80s and they become much better every day
I enjoy applying technology to business problems
