Just the fact that you read blogs and post in technical discussions shows that you care to improve your craft and don't just wait for somebody to tell you what to. There are no hard criteria to define "caring" but I like people to do something. Read stuff, know at least a little about the latest trends, think about ways to do things differently, try out things and so on.
- started programming in 1986 in AppleSoft Basic and 65C02 assembly language.
- graduated with a degree in CS
- I can bit twiddle pretty well and spent the first 12 years of my career doing C.
- I read blogs, post in technical discussion, listen to podcast, etc.
- I have up to date AWS certifications.
Etc.
But I don’t think I have a “passion” for development. I do it to pay my bills and remain competitive. I don’t do side projects but I will work late to learn a new to me technology or framework. I definitely don’t spend time learning frameworks or technologies that aren’t marketable.
