Most career advice tells you what to do. This blog is about why you don’t do it, and how to change that. I’m Ivan Palomino, behavioral designer, founder of PeopleKult and author of Expired? and Step Zero Before the Hustle. Here I write about what behavioral science really says about changing at midlife: staying indispensable when your company bets on youth, deciding whether to start a business after 45, and making the shift from manager to leader. No motivational fluff. Research, real cases, and practical tools for experienced professionals who want their next chapter to be their best one.
