Hi Yukala! Thanks for that really valuable information.
Sounds like you know what I'm talking about. One of the questions I've realized I was trying to ask is this -- almost any non-technical it's not that hard to pick out a purpose, at least not for me.
However, whenever I'm studying a technical book it's at times difficult. It's hard because say you're studying for an exam --"My purpose is to pass CISSP/MCSE/CCIE(whatever) exam so that I can make more money." To me this doesn't seem like a very concise or strong purpose.
You know what it's like if you're pretty good in IT. Half the time you're reading something because you are looking for a specific solution to a specific problem; this is ideal for stating a purpose.
The other half you're simply reading something because you're either curious about it, taking an exam, or something else that could be very broad. This is where I think I could improve.
I'm probably just thinking too much into this but was wondering if someone else had come across or experienced the same problem.
