One of my passions - which happily is also my professional job - is science. I think the reason is that even as it's sometimes hard and boring for weeks, there are moments when you see something or connect some dots that no other human being has seen or thought before. Then you're amazed. (then it get's boring again, but that's a different story)
So it's all about amazement. This week I wrote about something that really amazed me, even though for once it was not scientific: https://steemit.com/business/@sco/meet-the-viennese-eco-startup-growing-edible-mushrooms-on-coffee-grounds-english-german
