@ross That made me to reflect on the competitiveness:I never liked it, I had to push myself since the childhood to strive for more in answer to demands from parents, peers, society, but it always contradicted my desire for a cooperation and a way of doing things not in a rush.At the uni my group mates were involved in the uni, regional and then state-level ACM ICPC tournaments, where I failed at the initial stage just because I couldn't develop a solution well while under stress.(Interestingly, I behave well better than average in an on-call incidents type of situations, but that's another story).
