人多的场合，老是不喜欢说话。能改吗？我24。

[please forgive me, i have to type english because of our school computer.]
as far as i know, it is common- not only you, but also most adults, in other words, most asians. i am studying abroad now, and i find that those who usually raise questions, say their opinions, so whatever, interact with the instructors, are mostly western students, really few asians. that is true- because (e.g. americans) when they were very young, their school had a class named "presentation" that trains them how to feel free when speaking in public etc, but our school do not. plus we are "含蓄" :)
but "if you want to do it, you can do it". when i want to ask a question in class, i just ask it. it is cool and feels good. i am not a quite out-going person or a social person, but i do not wanna be shy.
you may speak facing mirror, to your family, to your close friends first. i think you will get help and make progress step by step.

可能是因为老了的原因。可惜老了不能变年轻，只有年轻可以变
