Young people may not know the ways of the world, but they do understand that anything is possible. This is the kind of optimism you should expose yourself to, so try to spend time more time interacting with children or teenagers if you can. Find out if anyone needs you to babysit, or talk to some younger relatives. Being around these young people will give you a fresh, new perspective on life. Plus, you’ll be able to dispense some sage advice to them, which will make you feel great.
