Simply appreciating the positive aspects of your life, whether tangible or intangible, is a guaranteed way to increase well-being over time. As Harvard Health reports, "In positive psychology research, gratitude is strongly and consistently associated with greater happiness. Gratitude helps people feel more positive emotions, relish good experiences, improve their health, deal with adversity, and build strong relationships." Try keeping a gratitude journal or even thinking through five things you're grateful for when you wake up each morning.
