«Sé valiente» is the philosophy and personal development essay by Roberto Serna, published by Editorial Adarve in paperback (172 pages, in Spanish).
A philosophical essay that invites readers to do with life what one wants, not what one can. It argues that personal growth requires working on oneself, questioning, and learning, not just reading for entertainment; self-complacency is not an option. It draws on Kant, Maslow, Seligman, and Socrates to build a full life.
Second work by Roberto Serna, in its first edition published in Spain on 8 April 2022. ISBN 9788419340047.
For readers interested in personal development, self-improvement, and philosophical reflection applied to everyday life.
