Travel more. Teach English as a foreign language so you can afford to travel. Stop binge drinking. Try to find a silver lining in every problem you encounter. Don't get a dog or cat or snake until you are making enough money to afford one and have a pet sitter. Find three things you're grateful for every single day. Yoga and meditation on a daily basis. Wait to have kids. Have kids when you are well established in your career and have a supportive SO.
