So When to quit your job?
Salary
Most of the time people quit their jobs because they think the salary paid to them for their services is very low and they cannot meet the daily expenses with this job. Mostly, People who think like this have been working for 5-6 years. I have warned the new pass-out graduates and freelancers about this 
situation in different posts. If you fall in this category there is nothing to worry the world is open for hard workers. I have not seen in my life that a person doing hard work has failed to achieve something extra ordinary. If you quit your current job to join a new company that might offer you better salary. Keep in mind a day will come when you would not be satisfied with that salary also. So make a solid plan for yourself. When to quit your job is not important, Why you are quitting is important. This is good post for people complaining about salaries.
Job role:
If you do not love your job role you have already wasted you time. Unless, you were collecting money to do something that you love. For example some people do odd jobs to have enough money that can help them to start their new ventures. Do not do something that you do not love. You are cheating yourself 
by doing such things that do not satisfy you. This is worst crime in terms of professional career. But do not panic, do not quit immediately. When to quit your job Make solid plans about what you love to do and where you should be. Promise yourself that you would not cheat yourself anymore. Give yourslef a deadline to achieve some goals. For example “I will learn the skills that i love in 2 months”. I will quit when i get a job in that field. This would be easy for you to plan for your future.

New skills from new company?
This is one of the best decisions for quitting your job. Quitting current job to learn about new things from a new company is best decision. 
Because when you think about yourself you plan better for yourself. Your life ends when you stop thinking. So when you have a new offer from a company that you think would teach you new skills even if salary is less than current job, Go for that. Believe me it would help you in future and it is perfect answer to your question “When to quit your job“.
Had fight with a colleague?
Well, That is one of the many reasons people quit their jobs. Because seniors always quarrel and degrade junior workers to release their frustration. Office politics are very common all over the world. Either you should continue to bear these things or speak out loudly about your right. If you have already decided to quit make sure you inform the management and other officials about why you are quitting and how they can improve their office culture. But i would say you should stay there if management is supportive because you cannot run from every place. You should face the challenges. But make sure you let others know about the mischievous behavior of those people. In this case Exact time about when to quit yor job can only be decided by you and your ego. But again think wisely.
Want to be an entrepreneur?
Welcome to the club, this is the best decision you can make. Thank your amygdala for this beautiful thought. Job can never be compare with freelancing or business.

Or you have some other method of income you are ready to quit your job. Mostly people want to quit when they already have a good job offer in front of them. This is the best option.
