Here are some useful habits that can help you a lot in daily life:
1. If you want to be happier：
Talk with a positive person.
Express gratitude by writing down some good things that happened to you each day.
Laugh – even if you have to force it. The mere action of laughing releases endorphins.
Move your body (walk, exercise) for 20 minutes or longer.
Invest 30 minutes a day doing a hobby you enjoy and find relaxing.
2. If you want to manage stress more effectively：
Breathe deeply for at least two minutes. Focus on your breaths.
Stretch different body parts for ten minutes.
Listen to something calming and distracting (i.e. music) unrelated to whatever is stressing you out.
Detach from the source of stress (excuse yourself from a meeting, take a break from a project, remove yourself from an argument) for a five-minute break.
3. If you want to be more confident：
List three things you genuinely like about yourself. Read those three things out loud. Do this daily.
Stand up straight. Let your hands hang naturally at your sides.
Outline your thoughts/words before you enter an intimidating situation. Being prepared will help you feel more confident. Bring cheat notes if acceptable.
4. If you want to become more spiritually-minded：
Devote 15 minutes a day to reading a spiritual text (Bible, spiritual book, spiritual workbook.)
Join a group of like-minded individuals whom you can learn from and be inspired by.
Write out how a person you encountered that day could enrich your life journey.
Perform one thoughtful act of kindness for a stranger.
