Just remember we live in arguably one of the best times ever to be alive. Crime is very low, most health problems have a solution, child labour is non-existent and there are amazing things happening in all facets of technology and work and engineering.
Its easy to see the world as shit because shit sells ad copy. But we humans just sent a rocket to a space station and landed the booster back for reuse. We are using AIDS to, if not cure at least fight, leukemia. Heart disease, cancer etc are now on the run. The biggest mass murders of humanity? Polio, measles, smallpox? They are now epidemics if 100 people contact the disease. The kids born today are going to look at the early 2000's the same way we look at the early 1900's when nobody had electricity or running water and infant mortality was in the order of 40%.
Things get better.
