Being present is by far the best way to stop suffering. Stop worrying about your past or future and live in the moment. Everything will take care of itself, it is universal law.
As we get older, we have a social obligation to help guide and nuture the lives of younger ppl in any way possible. Idc what ppl say. You don't have to be a mentor, but you should always be mindful your status as an elder in the lives of children.
