Where to go or what to do?

Context: I'm currently a 20 year old college drop out, I moved country to study & I dropped out. I'm home for Christmas & I'm debating whether to go back or not.

So I have completed my Leaving Certificate and also a course after the LC where was a 'PLC'. I have some background in development and computers, I would class myself as knowledgeable on certain topics.

So I moved to 'x' country about three months to study 'Software Development' and I had an interest in it but I always was into the server side of things (cyber security/networking). I'm going back to 'x' in January to work as a 'Customer Service Representative' and also as a 'Bar Man'. I will be on good money but that's not the reasoning for this post that was just insight into my current situation.

One of the reasons, I want to move back to 'x' is maybe I could meet people in these types of companies and I could start low and work my way up? (This mightn't work at all). Or will I move back home and start college again for the next three years? (I don't think college is for me).

'x' is an island right now where all the tech companies are so if I got lucky and started in one and work my way up? Or I was thinking of moving to the USA or Canada? *I know what's the point, I literally don't have a college degree* I need some guidance on this, I'm so lost at the moment.
