This is a kind of blessing that your passion becomes your job or business. There are not many people who enjoy that blessing. I dont love my job but I have to do it forcefully to get pay for daily living. I wish my passion becomes my source of income like I love to write technical articles and if that becomes my source of income then I can perform better in that sector. You cant excel in job or business where your passion is missing. You wont find any example where a businessmen got success by doing it forcefully.
I understand what you're talking about, but I don't understand why you keep doing what you don't like? Is it because you get good pay and find it hard to find another job that pays the same?
I used to work at a job that I hated, but the pay was very good and I had to go to it for several years. In the end, when I finally decided to quit, I went to another job and at first I received less money, but in the end I managed to get a good salary over time, but the most important thing was that I love my job, I like it. I no longer have that feeling of forcing myself to go to work, sometimes I remember those days and it's terrible.
None of us have to do what we don't like, we can change it ourselves, but sometimes fears make us stay in the same place, sometimes we just need to take a risk and our life will change for the better.
