Hey, I am now working in a state-owned enterprises, doing the work related to the specialty, but dry for a long time more and more feel uninterested, always thinking can not change the industry to try.
Hey, I know how you feel. Work is really quite important to us, and it's easy to feel depressed and powerless if you're not happy doing it every day. But the fact that you're aware of the problem and want to seek change is a great start!
First, I suggest you take some time to take stock of your interests and specialties. For example, what are some of the things you like to do in your spare time? What are the areas that you are better at? Find out if there are any careers that play to your strengths and are interesting to you at the same time. This will help you get to know yourself better, so you can find a more suitable direction for your work.
It might be a good idea to talk to colleagues or friends around you and hear about what they are involved in and about related industries. This will give you a more intuitive understanding of other fields and may even reveal some new opportunities.
As a reminder, never quit your job in a hurry. Until you find a new job, it's safer to try to maintain your current source of income. You can use your spare time to learn some new skills or try to do some part-time work to gain experience and broaden your horizons at the same time.
I hope these suggestions help!
