Lots of people want to become developers who, like me, didn't go to school for computer science. The good news is: It can be done. Some of the most talented engineers and familiar entrepreneurs behind successful tech companies taught themselves to code. But, that doesn't mean it's easy. I was working on the support team at HubSpot when I started learning how to build software in hopes of becoming an engineer and I quickly realized you can't just dabble in programming. You have to go all in.
