Is this your hobby, or is it your business?
If the former, you have no problem.
If it’s the latter, your enjoyment is no longer the first concern. The idea that you only charge more for work you hate leads to you working on stuff you hate all the time, only making money from things you hate, and chasing away the fun projects to someone else.
I can tell you that as long as you keep this “I’m not worthy” attitude, you WILL fail at the business end of this. You have to have the stones to turn down a gig that’s too low, if you are in business.
It’s like baseball: if you just indescriminately swing at every pitch they throw, you will strike out fast. If you let a few outside ones go by, the pitcher has to work harder…
Translation: you are being measured at every negotiation, and if you don’t demand a minimum amount, they sure aren’t motivated to pay you more just because you have an honest face. You will either not get the job, or get too much work for the rate you quoted, to the point you will be LOSING money. Or, to add insult to injury, they will subconract work out to you, while charging some other client for you PLUS a big markup for THEM. THEY will get more business for giving good quality at what is PERCEIVED by their customer to be a fair rate; you will be slaving away for nothing by comparison.
Yes, it is hard to turn down ANY work if you need the money. But you are not going to grow if you stick with minimum-wage rates, and the longer you stay a “lowball”, the more likely it is that clients will pigeonhole you as only worthy of their lowest-level, cheapest work. I see people and companies doing really poor work sometimes, yet they are charging high rates, and not losing any business over it.
If nothing really challenging or high-profile is coming in, stick with the day job, save up whatever it takes, and make your own productions that are more ambitious. If you can’t find a place to sell them, at least they become part of your portfolio, and future clients can see you are more than they expected. Then you are not beholden to low-paying clients just to generate examples for your demo reel.
So, what is a FAIR rate to ask? That is the big question! It’s calculated from many factors. You could search the past posts here with the words ‘rate’ in the title, and get a book’s worth of good, detailed advice. The digest version: understand ALL the *true* costs of doing buisness before you set a rate, or you will always be charging too little.
