1. The courses on AI/Machine learning and blockchain (or anything that has do with 4th Industrial revolution) are great. Coursera is great for this.
The greatest impact was the combined effort of being able to do multiple courses (in so many different things) and being able to better understand different programming languages, technologies and marketing (SEO, ads, content marketing, referral marketing, driving sales).
Can't leave engineering. Engineering is the passion. I have a strong belief that all parts of business should be driven by engineers from development to sales and marketing. Yesterday I went to a meetup and I met sales people on the booths who had no idea on the product they were selling worked and how it could help others.
2.) If you don't have friends in school, go out to events, network. Talk to people, add them on LinkedIn. Found someone interesting online? Feel free to email them and get to know each other. Thats how I have built my network. Don't forget the nurture professional relationships. Your network is your networth.
3.) I have a 15000 people following, the articles that are of interest get viral. A few times I tried to post my articles on some FB groups. It did work out well but I don't do it anymore. Best is to just keep writing (you may post on Reddit, FB etc but be aware that you might get banned for self promotion).
3. 'The Lean Startup' and 'The defining decade' are the most impactful books.
