This is so true — I’m in this position right now — biding my time at my day job, which I hate but pays well, while I try to build my writing clientele. I’m currently doing customer service type work, and I’m beginning to hate it because many of the people I talk to can be very unpleasant. But I keep reminding myself that some day I’m going to have a lot of writing clients that I’m also going to have to provide good customer service to.
