Why would you sacrifize them anyways? Many people live and thrive despite depression. That thing goes in remission at times. Or lessens significantly.

postponing your dreams will not make you happy. or happier. If you gain years of knowledge and experience you will have them regardless your depression. And you can feel good about yourself. Pride is form of pleasure too, ain't it?

nobody does lobotomy anyways and THAT wouldn't make you feel more pleasure anyways.
