Back to Basics

Bridging the gap between expectations and preparation for the leader role.

The Harsh Truth of Leadership is that No One is Born Ready.

Mateo Berbejillo, author of the book Back to Basics

You were a great individual contributor, and now you’ve been promoted to lead. You’re expected to know everything, but the truth is, a huge gap exists between expectations for the role and the preparation you’ve been given. You are not alone. Author Mateo Bervejillo admits to having been a moody, micromanaging team leader on the verge of burning out his entire team, when he first became a lead.



This is not a book of abstract theories. Back To Basics distills 15 years of hard-won, often-imperfect experience into a straightforward, no-nonsense guide designed for immediate, practical implementation.

Drawing on lessons learned from leading teams of 5 to 170 people across the globe, Mateo provides the essential, foundational skills you need to build a happy, high-performing team and accelerate your own growth.

Inside, you will find basic, honest, and actionable tips structured around four essential dimensions of professional impact:

  • Managing Up: Making your boss your most important client.
  • Managing Yourself: Sustaining your drive and balancing your well-being.
  • Managing Teams: Mastering the core concepts of leading and developing people.
  • Managing Sideways: Building trust and navigating peer relationships.

If you are an aspiring or new leader, this handbook is your honest mentor, offering the clarity and direction to save you time and pain.

Use what is helpful, discard the rest. Enjoy the ride.
