What truly sets someone apart is not how many specific skills they learn, but whether they continuously upgrade their "fundamental abilities," which is essentially the operating system of life. To establish an advantage before age 35, it's best to start deliberately practicing this system in your twenties. First, manage emotions through cognitive restructuring, learning to change your perspective on things to control your emotions and life; second, replace pure self-discipline with behavior design by using motivation, ability, and cues to build stable good habits; third, establish a feedback loop that makes actions, review, and adjustments form a continuous growth engine; on this basis, improve decision-making skills by learning to think from the perspective of "how to avoid failure" to increase your chances of success; fourth, solve problems through interdisciplinary thinking, borrowing mature methods from other fields to achieve effective solutions; fifth, use the Pyramid Principle to enhance communication and expression, clearly and logically conveying your thoughts. Those who constantly upgrade these fundamental abilities are more likely to achieve long-term excellence in any field they enter.
