Anywhere you go, you can find (and solve) a Problem
One of the most striking things about life here is that I constantly find something that could be solved and it could then help people to have a better life. That is, there are Problems. I use the capital P to denote a real problem (or at least real by my perception) and to distinct it from a problem like whether all my hairs are in right direction today.
One can fully utilize the potentials, can realize him/herself, can make a difference, or even save a life. The only ‘bad’ thing about the existence of the Problems is that they often do not belong to the realm of what a computer scientist is trained for. Among many, the main reason is simple: no electricity, no e-anything.
Indeed, we computer scientists find problems-to-solve wherever we go. I just talked about this phenomenon with people at ACM MM 2006. Perhaps we really are more engineers than scientists.
