On what basis should we judge who is living the best life? Based on how happy they are? On how bright their future is? Or how fun their present is?

Who is living their best life and why?
Scenario 1: a person who is partying everyday, on drugs, no job, no future
Scenario 2: a person who is working hard for their future with a job, not partying or going out, no drugs

Is it wrong to do drugs, parties and not have a job or is it wrong to have a job and not do any parties and drugs
Wrong meaning ( change their ways)
Who should change their ways?
