You must clearly state the job that you hate, so that people can give an objective assessment of the decisions you make, nowadays in uncertain economic conditions, many people find it quite difficult to get a job, so talking about passive opinions is the same as making commotion.
I have been in a job I detested and although I somehow managed to stay at it for up to 4 years, I didn't even for once let go of my passionate hobby and other passive streams of income I was interested in at the time.
Today, one of my passive interests pays more than my salary. My mind has been yearning for a resignation, but opinions of others and family bears the message of patience with the job I so much detest for reasons ranging from inflation to fear of the unknown.
If you were in my shoes, what would be the best advice you would give yourself and adhere to in this instance?
Four years is a long time to keep you in that job, I assume you don't hate the job, but rather the saturation point that starts to emerge based on the rules that apply in your workplace. Even if my assumption is wrong, then you are the typical person who does not dare to leave your comfort zone, because what I understand from the writing you wrote is that this is a job you hate, but instead you have been in that job for four years. Anyone can give advice about the problems you are experiencing, but believe using instinct and assessing comfort at work are important factors in making a decision to stay or not.
The concept of living for the rich, they never think that income only comes from one job, they will do everything they can to expand their income from various sides. But apart from that, you have full rights to choose one that can make you comfortable, because sometimes wealth doesn't always make people calm in their lives.
