I am a software engineer and I use DDD (Domain Driven Development) Before becoming a software engineer I read books on Philosophy. The thinking methods are very important.
Well I really out of time here Maybe I will write more later :P
I'm currently about half way through, i think the book is geared towards a younger audience but i'm finding it really enjoyable.
Once you have a high level view of the highlights of philosophy, you can answer for yourself which philosophers to deep dive on.
Every fundamental topic that later philosophers discuss is there, and discourse is much simpler.
For full comperhension, some googling of greek terms is required, but it's not that big of a deal in the age of /r/philosophy and communities like that. Also, feel free to hit me up if you have any detailed questions :)
