You have a brain. You have thoughts, dreams, goals and opinions and they should be heard!
When I left home to attend a college 268 miles away I was shy, unsure of myself and definitely out of my element. My classes were small so my professors had plenty of time to get to know each student, one class in particular stood out. My professor wasn’t exactly the nicest guy but he knew how to get his point across. One day after class he pulled me aside and said “Your thoughts are important you need to speak up!”
It wasn’t an instant turnaround but I did start speaking up more and it has made quite a difference. So don’t be shy. Share your thoughts!
