Less happiness means not to pursue happiness unilaterally, let alone put your own happiness above the suffering of others. Being less happy not only means being optimistic, but also means not being ecstatic often. Being less angry means that everything is easy-going, and you can argue according to reason when necessary, but you can't be angry.
