Quitting your stable job for full-timer mining is really risky. Why not do it both? since you can also do that side by side in parallel.
I know it's a hustle in the beginning, but once you get it up and running you can just leave it and continue working normally.
Yes, checking once in a day is not hurt you, especially after you back from work or before sleep for instance.
I spoke this as I also do the same, I still working and I have a mining rigs that give me "bonus" profit to my salary
PS. I dont know if you means by quitting your job is to build mining farm with 500-1000 GPU unit or antminner like. That's completely different story.
