Beware of putting people on pedestals. Far better is to just follow people who do cool stuff. They don't have to be a "master" to do something cool that will inspire you.
Also a self-taught web developer here. My advice would be to make sure you learn the languages, not the frameworks. Once you know the languages, you can pick up the frameworks far easier and you can actually dig in and see what's happening.

I went to Bologna earlier this month and the only thing I had planned was a cooking course for one afternoon.

Sites like tripadvisor add convenience and their rating system, which allows people to filter out the ones that may be a mistake going to. (Although these systems have biases)
I wish my first development job was like this place. Instead there was a blame culture and I'd get told off when I made mistakes, eventually getting fired for not progressing quick enough.

Partially because some people don't want to spend that much money on something they'll rarely use (cheapest I found from a quick search on amazon UK for any of the Eco-Tank series was £185)
