Schopenhauer has been called a western Buddhist, likewise one could say Buddhists are just eastern existentialists, the real difference is cultural rather than philosophical as Schopenhauer also thought that one's goal should be to minimise suffering by forgoing desires.
I however disagree, to forgo desire is to reject oneself and for now that is not a luxury we have, it's like telling a gay person to just pretend they're straight, sure it's possible by it's by no means a solution when you merely trade one problem for another.
If to live is to suffer then suffer and enjoy bitching about it I say
