Shyness is a state of mind
1. When you start thinking too much about others.
2. When everyone's opinion matters to you a lot.
3. When you are trying to make everyone happy.
4. When you worry enough about what others will say.
Take a look at a kid playing, does he care what others think. No, he doesn't.
Tips to get rid of shyness.
1. Stand in front of a mirror and start talking. Use your favourite movie and practice one of its dialogue. I would suggest go for a movie called V for vendetta and practice the dialogues of V.
2. Talk to you friends and ask for their help and tell them to give you an honest feedback.
3. Go and start feeding stray dogs, cows and people in need, this will help you overcome your shyness.
I will be very happy to discuss more in detail. Let me know if you need more help.
