Has anyone quit their job with no backup plan?

I have decided that I want to quit my 9-5 job but I guess I need some reassurance and insight from people who have done something similar. I am planning on taking a 6-12 month break where I will use the time to try build my own business and also study.

A bit about my situation. I’m in my mid 20s, live at home, have $62,000 in savings, and I pay $200 in rent a week (includes everything besides groceries). I am budgeting $400 a week ($200 to rent, $200 to everything else). I don’t have any debt. I won’t be using my car much since I only really use it for getting to work and the occasional outing with friends. The only bills I will have will be my car registration in June and a car service scheduled for that time.

I currently work a job I don’t really care about. I like the people I work with but the job is an industry I don’t have any interest in (I ended up here during covid when my old workplace shut down – I was freelancing in the interim before finding my current job). My salary is $65,000 before tax, so it’s not like I’d be giving up a high paying job. Like most people my age, I am disillusioned with the traditional workforce and the way I have been priced out of the housing market has left me feeling like I might as well try pursuing my interests rather than the ever-fading “Australian Dream”. I don’t really have any worries about finding another job in the future because I’m not too concerned with what I’d end up in if this venture doesn’t work out.

So for those of you who quit your job to pursue your dreams, or those who may have some wisdom to offer, please comment below. How did your situation work out? Did you burn through savings quicker or slower than you thought? What was your situation like before you quit? Should I invest most of my savings and keep a small amount in my bank?

EDIT: Almost every comment here is in support of me quitting. I am going to do it.

EDIT 2: I have made plans to quit in the coming months and take the rest of the year off. Thank you to everyone for sharing your stories and encouragement.
