Letter to my fellow Software Engineers

I started working in mid 2012 as a software engineer for a multi national services company based in Bangalore as a post graduate from a very famed university from south India which was in 11th position when I started my studies there in the list of top engineering colleges in India. I graduated in 2012. Most of my classes felt like school mostly because of my department. Even in university campus I was not exposed to practical real world usages to sciences be it may any kind science. The internet was not accessible very easily at that time and exposure to online courses was limited to 0. I always dreamt of studying at Stanford some course related to computer science. I had to take work a job than study after 2012. Its not fair to study after getting a master's degree. I shouldn't say this but I was limited by my surroundings, society, everyone in colleges, my family and relatives, mostly everyone I know of. The thing is you have to work and earn somehow after you complete your education. This is true in ideal
