I’m behind the scenes in this industry and agree with the PP - this is one of the hardest industries in the world and if you don’t go to drama school, you are miles and miles and miles behind your contemporaries who did. Not only in terms of honed skills but also in terms of contacts. Agents, casting directors, directors, other actors meet at drama school and people employ their mates / see other actors on the recommendations of their mates.
What do you go and see at the theatre? Actors / related careers go to the theatre A LOT. Whether West End or Fringe, the actors etc I know go two or three times a week. Know. Your. Industry.
You need to go the classes if you can’t yet go to drama school full time. Are you in London? You mentioned evening classes but all are not created equal. Not sure if it still exists but look up The Poor School.
Agree with the removing all Extra credits from your CV. It’s not considered a good look - it smacks of someone who knows nothing about the industry. Like someone who has no respect for the skill & talent involved in acting and will see you instantly on the NCB pile.
I know dedicated, talented, passionate actors who never quite make it. You need to want this with every bone of your (highly resilient) body and even then you probably won’t make it. You need a hide thicker than Johnson, the self belief of Trump and the talent of Joaquin Phoenix with the looks of a supermodel.
That said, someone’s got to get the gig so work hard, develop your skills and it could be you.
