HOW TO BUILD MENTAL STRENGTH

Summary from the TLDR Founders newsletter

Clear thinking requires four strengths that most people lack: self-accountability (taking responsibility instead of making excuses), self-knowledge (knowing where you're actually competent versus where you're just confident), self-control (managing impulses so you're not sabotaging your long-term goals), and self-confidence (the balance between earned competence and aspiration). These aren't abstract ideals, but muscles you train daily. Positive habits become automatic defaults that compound over time, while the right role models show you what's possible without you needing to compete with them directly.
