I recently left a job over something stupid that I did. Never knew how good I had it until I am no longer working there.
Am I going to be OK? Yes because I have an adequate funded emergency fund. This is because I delayed gratification by saving and investing money rather then having a car or buying things expensive clothes. Having an adequate funded emergency fund allows me to sleep at night. You never know when an emergency is going to happen whether voluntarily or involuntary. This doesn't negate the fact I made a mistake leaving my job.
What would happen if I didn't have an adequate funded emergency fund. I would have no way to pay rent or pay for food. Since I left the job, after 2 weeks notice, I do not get Employment Insurance as I left the job on my own.
The moral of this is that don't jump to quick and to something you will regret later. I am glad I have an adequate funded emergency fund.
