I'm a self-taught web designer.
When I started my way I had neither money nor opportunity to study at any good school. I tried to find some nice online courses in Russia, but all the knowledge they provide could be easily learned for a week or so by simply searching the internet. So I wasn't satisfied.
Prices for studying at any European school were exorbitant for me. That's how I chose being self-educated.
Self-study is a long long way, which includes searching information 24/7, reading tons of articles, watching tones of videos, meeting lots of people who have achieved something in the field you are interested in to seek their advice, and so on.
This article is for people who chose the same way of studying, or for anybody who wants to improve their knowledge regarding design thinking. To save your time for seeking something to read, I want to share with you some books I found useful.
