Teaching is itself a good job but you are not seeing much career enhancement scope in it and want to change it and switch to some other career. One important thing is that if your age eligibility is there then you can think of appearing in some competitive exam as most of the positions and jobs today are through the competition only. Some of these competitions are in state administrative services, central subordinate services, Railway services, Postal services, posts in PSUs, and many more. In their entrance exams, some papers are related to the general knowledge, general English, aptitude related, and some logical questions etc and to that extent the preparations done by you would be common to all and you can take that advantage by preparing for some of them as per your interest and liking.
If you have a good command of teaching and as a paying job you like it then there is a possibility to look for employment in high end online/offline coaching centres which are earning good amounts of money as a large number of students are joining them who are preparing for prestigious exams like IAS, judiciary, or state public service etc. Teachers having proficiency in Arts. Culture, History, Political Science, and many such subjects are required by these coaching entities.
If you have an interest in business and want to establish your own enterprise then there are many business propositions which require to be considered in today's business environment. It is to be noted that for doing a particular business it is not necessary that you have the full knowledge of that area because today you can hire people at a nominal cost. The only thing is you should be able to manage the whole thing from financing the business to its marketing. So entering the business arena is one thing which many qualified and educated people do not consider as the first option but it has its own worth. A simple example is to open a service centre for various routine services like printing, photocopying, high-quality printing and album making, delivering the product to the customers online, accepting original documents through Whatsapp or email and completing the work assigned and submitting the product to the customers etc. This is a simple example but can be extended to so many other ideas. You can raise the money through bank loans or self-savings.
