I dream in abstracts and concepts and avoid anything with substance.
If we take databases as an example. My interest stops at tables and what you can do with ANSI SQL. What features each database implementation has is not really important to me. I can look that up if I need it later.
The disadvantage of this approach is that I'm dependend on my team to complete anything. Luckily I like working together with people.
The advantage is that the knowledge I gather isn't easily outdated and it can therefore accumulate over time. In other words I don't have to start from scratch every other year by learning new technologies.
