About the future?

So… I was finally able to figure out what I wanted to pursue professionally. Before, I wasn't sure what I wanted to be; I was always changing what I wanted to be once I grow up. Until one day, I became obsessed with becoming an actor (It should be mentioned that it had never occurred to me to be one). And since that day I started thinking about it and even put that on my life plan. It used to be plan B but now is the A one.

But I started doubting about it since there are so many problems that can stop me from becoming one and that kinda terrifying…?
