Useful tips and habitsDrink more. Drink a glass of warm water with lemon every morning on an empty stomach. Put a bottle of water on your desk at work.
Try new things. Plan 2-3 small experiments for yourself each week: a new movie genre, a different cuisine, an unusual hobby or activity.
Do good deeds. At least once a month, help someone in need: send money to charity or participate in a volunteer event.
Enjoy the little things and be grateful. Take 5 minutes in the evening to write down in your journal what you are grateful for today, what made you happy.
