12. Gardening (do something in the garden)
32. Drive ( This has always helped me too... Gosh, I miss my car and the music so much)
I am listening to
Tu hai Aasmaan mein ( Jhankaar Beats ) ... still in love with this song even after 5 years...
and I want to listen to Nirvana (Come as you are)
some more tips... take as many as you want per day even without a bad mood :)
11. Do something with your hands... gardening was one... cooking is another... maybe making clay objects too...
19. Sing loudly to your favorite music... My choice of songs would be Sa Re Ga Ma ( from Chupke Chupke), Baajoooooo (Chalti Ka Naam Gaadi), Jaaneman Jaaneman Tere ye do nayan, Do Dewaane Shahar mein, Zindagi Aa raha hoon main, Hum Bekhudi mein Tumko Pukare Chale gaye... and lots more...
