Few months ago at end of what seemed to be the most stressful day of my life (yes, crap happens at my side of the world too ;)), I had a phone conversation with my attayya. At the end of the call she said, "Sowjanya, keep saying this to yourself every night before you go to bed. 'I want to be happy. I deserve to be happy and I am going to be happy'." It hit right in the head for me and helped me quiet a bit. Every time I get annoyed, angry,upset or sad I use the happiness mantra she taught me and everything seems to fall in place magically :). You can use it when you are happy too ;).
I also have my little brat to help me feel better any time;).
