It's not impossible. Civilians do it regularly. Like learning to fly, you have to have the "it" to make "it" happen. Some do "it" and do it well.
The improbable part is something you, in particular, have to decide- for your unique situation and personality.
Analogy- when you're PIC, you're all alone when the "rubber meets the road." If you're lucky you'll hear voices, offering advice, and if you're really lucky you'll crash (or not), publicly- and make the evening news. But- you'll live or die with what *you* can do for yourself. Nobody can help you. You'll decide what's a realistic expectation, and you'd better not wish yourself to death....
Don't fool yourself now, either. If you're unsure of your ability to do this, quit now. Write it off as life enrichment and cut your losses.
I'm not an airplane driver, but my best guess is that it's no easier to get a paying seat without swinging your wings. You might hear more success stories, but that's because there's more fixed wing jobs. There's also more fixed wing pilots...
My impression is that the rate of success is about the same.
Final thought- I love my job, and have since '68. But I had no choice- I HAD to do it. If you have to ask, maybe....
