The pursuit of love can be one of life’s most difficult undertakings, but it can also be one of the most rewarding. Love is a complex mix of emotions and experiences, from the profoundest virtue to the simplest pleasure, and it can vary over time.

From poems and songs to movies and novels, romantic love has been a prominent motif in human culture throughout the ages. But what is it? How can we understand it and how does it differ from liking someone? And, more importantly, does it contribute to happiness?

The ancient Greek philosopher Plato wrote that “love is the highest form of power, and it is the foundation of all knowledge.” He believed that love could transform individuals and societies. However, he argued that love must always be kept in check and balanced by reason and wisdom. Despite the difficulties of finding and keeping true love, it is possible to develop healthy relationships that help people thrive.

Biologically, we think of love as a mammalian drive similar to hunger or thirst. Love is a combination of hormones, neurotrophins, and pheromones that create a feeling of attachment and connection with another person. In addition to these biological influences, love is also a cultural and psychological phenomenon.

When you’re in love, your brain is wired to see and feel the world differently. Research suggests that the experience of falling in love triggers the same brain regions that activate when you’re hungry or thirsty, and the feelings that come with this rush can be quite intense.

You might find yourself more generous and willing to make sacrifices when you’re in love, as you’re inclined to put the needs of your partner above your own. In the first rush of love, this can feel very fulfilling and give you a great sense of euphoria and well-being.

Then, as the initial euphoria subsides, you can begin to realize that loving another person is actually a lot of work. It requires selflessness, compromise, and the willingness to forgive mistakes. The work can also include resolving differences, maintaining trust, and growing in maturity.

Happy people prioritize spiritual/non-materialistic values, such as caring for others and themselves, respecting differences, and making a difference in the world. They value experiences over possessions and are kind to themselves by getting enough sleep each night, which is essential for optimal performance, cognition, and physical health.

They are also forgiving of themselves and others, acknowledging that everyone makes mistakes. They have a good-natured sense of humor, and can laugh at themselves and the absurdities of life. They know the importance of letting go and moving on, and not allowing themselves to become stuck in negative thought patterns like envy or jealousy. They are able to connect with other people and are open to new experiences and adventures. They also prioritize their mental health, taking care of themselves by avoiding negative thoughts and behaviors, such as gossip or complaining.
