Happiness is subjective; each person goes through life differently.
Yet we have perceived as having materialistic things as happiness. The more you have the happier you will be. But is that true? How many rich and successful people have said they suffer from depression, that they felt unhappy in everything? Jim Carrey, Ellen DeGeneres, Cara Delevingne, Johnny Depp, Eminem, Chris Evans, Harrison Ford just a few celebrities that have admitted to suffering from depression and other mental health problems.
The more you have, the more you want, and that cycle never ends. We have lost all connections to our souls, everything we do we do for a reason. Maybe we should simply forget the rewards and do what makes us feel good. Take a nap if you feel like it, leave that dreadful job and take that cruise. Travel, love, work for passion, not money. Work to help others, work to save the planet. Happiness is subjective, each person cares about different things. Find what you care about and follow that path to the very end.
