Analysis paralysis

I also have a tendency of over analysis specially in the subjects I like. Economics does that to me and that leads to improper time management on my side. I think, our LT also bears with me all this one time or the other. In the same subject, we had to make a short presentation without a PPT. This was an instruction given just three hours before the presentation. I feel I have good communication skills and so I took on the challenge with one of my team mates. We decided to use the chalk board instead. I guess that worked in our favor as none of the teams used it. Moreover, we had some reference data on the board, during the Q&A sessions.
