This collection of lectures and essays by Alfred Adler brings together one of his most important ideas:

That the desire for superiority must be balanced by social interest.

Adler did not believe that striving to improve oneself was wrong. In fact, he saw it as a natural and necessary part of being human. We all want to grow, to feel capable, to overcome our limitations.

But problems arise when that striving becomes self-focused—when the goal is not growth, but being “above” others.

Without social interest, the drive for superiority can turn into:

• Control
• Domination
• A need to win at the expense of others

With social interest, however, that same drive transforms into something entirely different:

• Contribution
• Cooperation
• A sense of belonging within a wider community

Adler defined social interest as the ability to care about others, to feel connected to humanity, and to act in ways that benefit more than just oneself.

In this sense, true strength is not measured by how much power you have over others—but by how much you contribute to the world around you.

This idea offers a powerful lens for understanding both healthy and unhealthy behaviour.

It explains why some people, despite appearing strong, feel the need to control or diminish others. And it highlights what is missing—not ability, but connection.

At the same time, it reinforces something essential:

You do not have to become hard or self-centred to be strong.

You can grow.
You can succeed.
You can become more—

without losing your empathy, your humanity, or your connection to others.

In fact, according to Adler, that connection is the very thing that makes growth meaningful.

Because in the end, a life focused only on superiority is isolating.

But a life grounded in social interest is one that truly belongs.
