Ok I'm not an actor but I can answer your question.
The answer is yes! You can fulfill your dreams.
The question you should be asking,is. Am I willing to make sacrifices to reach my goal, to fulfill my dreams of being an actor,
It is not enough to just want to be something,it's the amount of dedication you can and will put toward the end result. Leaving loved ones, losing sleep,lose of free time, lose of friends in order to go to practise or classes,and forget a relationship it only blocks your path and destracts you from total concentration.
I have learned this from the dreams I've had to sacrifice since a young age. ie.(getting married with children) I had to redirect my path to be a parent. My dream was so much easier!!!
Good luck my friend and never look back!!!!
