Reddit mentions of Action Day Planner 2019 - #1 Time Management Journal & You Get Things Done - All Your Thoughts, Goals & Actions in One Place (8x11,Thread-Bound,Black)

Hey fellow failed artist!!! I've been in almost exactly your shoes, with the exception that I wanted to be a musician (the next Primal Scream or Chemical Brothers) instead of an actor. It's equally tough.
The closest I got was a fairly decent project studio where I had paying customers (enough to keep me in new gear when I needed it) and an admin job within the music industry, which I "worked" at for 10 years.

If you're like me, then drugs are a no go. They just can't happen. They'll only fuck you up. So if you want to make any progress in life and you haven't stopped yet you need to stop taking drugs now, stop drinking too if need be; especially if that leads you on to drugs during the night, which in my case it usually did.

In my case that meant I needed to stop hanging around with my friends for more than six months, unless it was a drug/alcohol free event, which was never the case. And when I did start hanging with them again it was only if there was no weed being smoked (passive weed smoking is a great way to get drawn back in). Also if we were out for a beer and coke or speed arrived I'd finish my beer and make my way home.

Anyway, if drugs is still a thing in your life you need to stop it. Expect that process to take at least a year. If you fall off the wagon one night just climb back on again. If you don't stop with drugs, then yes, this is it for your life from now on, most likely.

Next - no one is going to change you life for you but you. Get that into your head, it doesn't matter how hard or easy your life has been, how wronged you've been or how many chances you did or didn't get in life - it's ENTIRELY on you, no one else.

Start thinking long term. If you want to change something, like move career to something more meaningful, you need to have a long hard think about that. Forget about fame, forget about getting rich, forget about easy street. Look for something you are interested enough in that you are willing to put in the work long term and start taking MEANINGFUL steps towards that goal. Does that mean going back to school? some other sort of training?? beginning as a hobby? joining local community groups or going to meetups maybe?? Start there.

If you're really hating your job right now, can you look for something even slightly more related to the field you're interested in to help you along the path then do it. How about joining a community drama group, and do acting as a hobby while you fix yourself?

Truth be told, when I was at where you are at now it took me almost 3 years to clean myself up (drugs, drink, paranoia and other fallout after nearly a decade of drug abuse) to the point where I felt confident enough to get a job I was interested in, then I worked that job for almost 10 years until I got bored and finally made the decision to go back to college at 35 years old. Now I couldn't be happier. Things are great.

But it's all down to planning, long term thinking, grit and determination.
Also, get proper sleep and exercise. Seriously, if you're not doing it already it'll make a massive difference.

I also would have been lost without this day planner. It helped me maintain the focus I need to get where I needed to get, check it out and give it a try. I still use one daily:

Read the instructions and philosophy of how to use it and get started.

Finally, as others have said, if you're trying to avoid drugs then working at a beach bar isn't ideal. But otherwise, working at a beach bar is fucking easy if that's all you want. Save a few grand for tickets, a few grand to get started and away you go. It's not rocket science. You could probably find a job before you leave if you really wanted to.

Edit: A quick edit for the "Hah, yeah, like it's so EASY to just get a few grand together" crowd - yeah it is, OP had no problem getting money together for drugs/alcohol/cigarettes, drop any one of those and save the money it'll add up quickly.
