Truth. When first starting out I always had the thought "OK, I'll go full-time once I hit $2k MRR", or 3k MRR, or 4k, "that'll be enough", but once I'd hit that mark, I'd realized I just couldn't do it because as my MRR grew my costs followed. I had to hit $8k MRR to be able to go full-time on my business, and even then that was taking a 60% pay-cut and a big leap of faith.
