"You have two assets that you can never get back once you've lost them: your body and your mind. Most people stop growing and working on themselves in their 20s. Most people in their 30s are too busy to worry about self-improvement. But if you're one of the few who continues to educate themselves, evolve their thinking and take care of their mental and physical health, you will be light-years ahead of the pack by 40." (Stan, 48)
It follows that if one can still change in their 30s — and should continue to change in their 30s — then one must continue to work to improve and grow. Many readers related the choice of going back to school and getting their degrees in their 30s as one of the most useful things they had ever done. Others talked of taking extra seminars and courses to get a leg up. Others started their first businesses or moved to new countries. Others checked themselves into therapy or began a meditation practice.
As Warren Buffett once said, the greatest investment a young person can make is in their own education, in their own mind. Because money comes and goes. Relationships come and go. But what you learn once stays with you forever.
"The number one goal should be to try to become a better person, partner, parent, friend, colleague etc. — in other words to grow as an individual." (Aimilia, 39)
