How would you describe yourself, personality wise, now? And also, YOU CAN DO IT! One of my biggest goals is to do motivational speaking one day, all of the traits you just named off ARE who you are meant to be, you just have to put yourself out there and be yourself! You should go after your passions instead of falling back on the, "I can barely speak fluently in front of people, so what's the point" excuse. GO FOR IT and of course there will be points where you're embarrassed and frustrated and angry, but in the end you'll know you had the bravery to conquer your fears. I'm taking a public speaking class right now and it's been wonderful for me, start little and get out there and be the amazing person you're supposed to be!
