what is your opinion about your thinking power? is good,or not

It varies, trust me it does. Sometimes I'm able to think real quick, other times I'm at the mercy of my growing senility ;p. Its that, but also I know quite a lot and I'm still learning, so it does take a bit to sift through some of it.

I can be a very deep thinker at times. I tend to be way too overanalytical too. I can think of stuff that no one can come up with the answers to and it drives me and everyone else crazy.:P Being a thinker is not a bad thing. My sister is like that too.

Without a truly effective or fool-proof barometer/gauge of my thinking power, I could only speculate as to my current thinking power. In my humble opinion, I believe that my thinking power is quite good because I can logically reason, creatively think, and even objectively examine various issues, provided, of course, that the criteria I've enumerated could really be considered as the generally accepted criteria to successfully determine one's thinking power.
