For a lot of reasons, I do not like any activity which constrains me to be only a gyan giver - There are a lot of professionals like that, teaching,hands off vc investing, consulting etc, where one is not involved in the operations per se but he bets on various aspects from the spectator stands. In this regard, I came across a quote from Theodore Roosevelt which aptly sums up my feeling :

It is not the critic who counts, not the man who points how the strong man who stumbled, or where the doer of deeds could have done better, The credit belongs to the man who is actually in the arena, who strives valiantly, who errs and comes short again and again, who knows the great ethusiasms, the great devotions, and spends himself in a worthy cause, who at best knows in the end of triumphs of high achievement and who at the worst, if he fails, at least fails whole daring greatly so that his place shall never be with those cold and timid souls who know neither victory nor defeat."
