I don't want to get a 'real' job
Why not? Do you think that it will consume most of your time if you have a job?
Yes, I wouldn't want to lose my freedom and all the fun i'm having.
It's responsible to have a job. If you don't have one then you can't buy the things you want.
It's fine but what do you do when boredom hits?
If you're bored then you can try to find a different job that you are passionate with and you will not be bored of. I hope that you will find a better job so that you will not be bored and think of it as something that you are being responsible of having and at least think about the money you will earn having freedom on buying the things that you want to buy moving forward.
