Stress can kill happiness. If you're not well-off financially you'll be stressed. If you're not healthy you'll be stressed. If you're not loved you'll feel alone, depressed and stressed eventually. Also I think if you focus on any one of those too much, you may lose at least one of the others. So balance is important. If all a person does is chase money, the love in their life may suffer for it. If all someone does is focus on love, they may end up a poor poet on the streets lol. Thanks for sharing.
