Opinion piece by Genís Roca. An optimist isn’t someone waiting for luck, it’s someone who thinks there’s still margin to act and is willing to try, with some joy if possible. Pessimism destroys energy; chronic anger curdles into agror tòxica. But the problems we face may demand a new mutation of the species: optimistes emprenyats, angry optimists who stop being so polite and firmly kick the useless out of the critical seats. Without bitterness. Simply with contundència.
