Mindfulness only needs 30 minutes from you, and I am sure you can give it because it is all about making your life happier and better for lifelong.
Do you have a morning routine of using your smartphone constantly? Change it! Do other things in the morning that open the doors of happiness and peace.
If you don't have any bedtime routine, let me tell you that you can set a routine like relaxing with your favourite activity, removing unwanted items from your handbag, etc.
Have lots of Midday activities that will give you nothing but happiness? If not, you can start reading books for positivity, make your own food, Listen to a Podcast, etc.
Sometimes, it's nice to go outside alone for lunch or dinner. It is another best way to live a happy life. Go to your favourite spot and try your most-loved dishes.
