About the author

Built from real ADHD life

Mateusz Karpinski writes the books he wishes were easier to find: clear, practical, and forgiving when the day changes.

He and his wife both have ADHD, and they are raising two young children. Plans get interrupted, energy changes, and starting over is a normal part of family life. It is not a personal failure.

Every Dopamine Friendly book is designed around that reality: fewer demands, clearer next steps, and useful support you can return to after a difficult day.
