How do i become more social and bold?

i used to be kinda like that...well you really shouldn't care what people think about you but that doesn't mean to be totally careless about it. try making people laugh and be friendly and nice people will see you are a good person and will hang out with you. don't just stick to one group try talking to other people too. this will take time don't expect too much show people you are a person to have a great time with but also the one that anyone could trust
