<prompt> Human: Hi,I am 24yo and I work as a self-employed mobile developer iOS apps. I live in Portugal its EU, here you can survive with 500-600 only rentbasic expenses and with 800month you can live good enough.As every freelance activity my revenue fluctuates depending on the clients I have. Also if I have health issues that make me impossible to work, I cant earn.I never went below 550month, having a good period with 1000 in a month. Average monthly revenue is 800.Note: I am in Europe so no need to pay retirement or health insurance, I pay contributions to the public social security system that will end up being my retirement and we have public health system.My very long-term objective is to save enough to buy an house.My concern is about savings though. Every month what I do is putting aside the part of revenue that exceed 800 the amount for having a good enough quality of life, so lets say, I earn 1000 in a month, I put aside 200 to the savings account.Unfortunately though, in the last few months I had some extra expenses such as: In January, had to buy a new Mac after the old one died after 6 years of life. It was an emergency because without computer I cant work. Last month I closed the phone plan of my origin country. The early termination costed 70. At least I dont have to pay 25month until 2019. I got a good phone plan from a local phone operator here. By May, I will have to pay 200 to an accountant, a one-time consultancy for closing the last bureaucracy things in my origin country. Any freelancer here, that can share their experience with savings and sudden urgent expenses like having to replace their work computer?My fear is having to deal with an urgent expense while in a period of thin freelancing revenue.--Budget of my current monthly expenses:rent - 400netflix music - 15public transport card - 35sport - 15phone plan daily use - 1575gb hotspot plan work - 20supermarket - 80misc - 100fun - 50total - 730EDIT: I corrected a mistype in the expenses, I wrongly wrote the hotspot plan cost was 200, but is 20.  <response>: Honestly, earn more is the simple solution. Not particularly helpful, but you need to build up a buffer to protect against unexpected expenses and the fastest way is to have more money going in to the buffer. It sounds like the expenses you have are as low as a person on their own can get, so youre doing well there
