1. Join the slow movement.

2. Meet a lot of new folks. Find meetups happening that have nothing to do with your field. Buy lunch to one new person everyday and have long conversations. Go on a road trip maybe to meet and connect with all your old college friends.
3. Read good fiction. Read magazines that have nothing to do with your interests.
4. Travel. But without fix leaving dates. Slow leisure travel.
5. Eat healthy. Exercise. Sleep well.
Inspiration for this post taken from the quote:
"There are four ways to know much: live for many years; travel through many lands; read many good books; and converse with wise friends." - Baltasar Gracián
