It was late 2018. I was coming out of a teleconference when I had a quick random chat with one of my senior colleague. He had just shifted back to India after a long stint in Ireland and was explaining me the knowledge he gained recently in scrum/certification/cloud, i.e., overall study in general.
It was an eye opener for me.
The 15 mins talk with him kind of change my perception on study, in knowledge and life,in general.
