Buy Experiences, Not Things:
In some ways money can buy happiness-when you splurge on a vacation, rather than shoes for example. Experiences lead to lasting memories, which can result in satisfaction, meaning, and a solid sense of self. Spending on leisure is smart because activities generate social connections, and strong connections contribute to happiness.

Maximizing Your Time.

Just keep moving forward, no matter what.
