The thing is that the details of how to build something are worthless compared to reasons why you need to build something. I spent my time learning how to build things. Whereas my friend spent his time solving an actual problem.
If you want to create something useful then it’s crucial that you learn to identify the reason why first. You begin by asking good questions about who will use something and how it will improve their lives.
That's something to remember to tell the next person who says to me:
Also, you’d be crazy not to use a host like Netlify and github/bitbucket integration (another thing to learn, of course, but worth it if you’re building any software anyway.)
