Are you the shy type or you are the bold and courageous all going kind of person? Regardless how you are do not be worried too much just because there are different temperaments that every individual posses. The fact that you can't do somethings does not mean you are uselessness. You can learn the act of being confident and doing away with shyness. It's a gradual process just set your mind to it that you are going to make a difference. Baby steps will get you there.
Now look at me wo would have taught I will come out as an outgoing and lovely girl who is all out and outspoken. It took me some baby steps to get to this point where I can stand before hundreds of people to address them and be a great inspiration to them.
Just be open minded and set you mind on developing any skill you want to develop in.
Thanks for having a read. Have a good day.
