I feel like I’m wasting my life. Should I quit my job?
If you are not happy with your job, then you should quit. I’m often more neutral and moderate about quitting jobs, but staying at a place where you feel like wasting your life is of no use. Let’s discuss more.

I’m assuming you’ve given this consideration, many times, due to frustrating problems associated with your job. If you think that the reasons which have made you decide that are permanent, and there is no quick solution to them, then you have a pretty clear decision to make.
At the same time, you must prepare yourselves for the financial and mental consequences after quitting the job. In a scenario like today, where people are losing their jobs, you are lucky enough to have one. But don’t use that as an excuse to stay in an unproductive, dead-end situation. As per my experience, I would recommend keeping a backup job ready first, but it’s your call.
If you already have alternatives to your present job, then you shouldn’t make your life more stressful by staying in your present job. Whatever be the situation, you should work upon what I call 3S. Those 3S are helpful for anyone who has quit a job, planning to quit, or believes in strengthening the professional profile and securing their future.
As there has been a sharp increase in the number of people who are not happy with their job, I have made a post to help all such people: I’m Ready to Quit My Job YESTERDAY, How Do I Do It?, covering those 3S and some other things that I believe are helpful in your situation.
In conclusion, life is precious, and one should make their best efforts to live it fully. Don’t waste it upon something that doesn’t interest you.
To end, I’ll quote something I once heard from a smart old guy. Not famous, but maybe he should’ve been. “There are lots of ways to fall down, and none are as painful as staying there.”
Good Luck!
Thanks,
