I am renting an office in a coworking space so I can have a place to "go to work" rather than working from home. It adds a routine, it gives me separation between work and home, and it's nice to have human contact over the course of the day.
I currently have a full time job, and enjoy the periods where I am left to get on with my work, but all to often the non-technical users will not read error messages, and ask me stupid questions to "fix their excel". It makes it impossible to work on certain things, like learning a front end framework when you are being bugged with trivial tasks like this every half hour. (The fact we are still using excel as a data import solution bugs me as well, as I have complained about the lack of reliability for a long time now).
So freelancing would hopefully allow me to do the sort of work I want to do. I know there is a whole load of other stuff I will need to manage, but it must be better than fixing formatting issues in excel.
