Awesome idea The thank you thing really helps. I've tried to curb the amount of self-deprecating commentary to compliments and just smile and say "thank you." Eventually I get better at complimenting others but for now the most important part is to just accept other people's love. As for other things to... keep rolling (ahahahaha sorry)

Standing up tall with good posture actually helps a lot (Amy Cuddy: Your body language shapes who you are | Video on TED.com).

Things like, walking with your head held high is great. Don't look down at the ground (a sign of low self esteem) but upwards and smile at people. Even eye contact helps because you make a connection with someone.

Always treat yourself when you do something great (like ice cream and chocolate) even if it's something small like getting out of bed on a tough day to something larger like completing the important items on your to-do list.

And always make time to do what you enjoy (when you can find things you enjoy). Like hanging out with family. Or watching your favorite movies. I personally get it from flying kites haha.

Anyway, thanks for this
