1. My engineering ended in 2013. I was shit broke. I started doing online courses in 2016. Till now I have done 51 online courses in different things and just a month ago I got moved into a DevOps role (from a WordPress developer role). $0 invested in it.
2. The other best thing is growing my LinkedIn network. I grew my network from 200 people to to 15000 people (most of which are founders and recruiters). I invest time in writing articles and sharing new opportunities via LinkedIn.
3. I started reading a lot of books (related to tech and business).
4. I started emailing, tweeting to people (and getting heard by people like Jimmy Wales, Elon Musk, Tim Draper, Craig Newmark, Charlie Cheever) etc. This helped me grow exponentially.
5. Planning ahead. I started visioning life 30 years ahead. What was what I wanted. If your goals are clear, it will be much easier to find the path.
6. Ask, ask, ask. I asked a lot of questions on StackExchange, Reddit -> r/webdev and Hacker News. Whatever I plan to do, I take feedback from these groups. I have also joined Slack channels of professionals from different groups where I talk and take feedback. From ideas to resume review and career guidance.
7. Anyone that could teach me, I made him/her my mentor and listened to them and acted on their advice. Everyone I work with (founders, coworkers etc) see the passion in me and tries to mentor me. The trick is to always be willing to listen to others and keep connecting dots.
