Dream

We only wanted to be in favourable conditions because main goal is to survive(by anxiety,pain,depression)and reproduce (by pleasure)!!love which is not goal that's only happen for children!!. But we are concious about future.our mind can imagine fake pleasure (after imagination when we come in exteroception that's hurts we think we loose all that I have)and suffering in future so that can be a fuel to hard work in present.so, we can hard work(because there is competition for limited resources)in present for better future(domination).
