How to change a profession
Think about what you do not like about your old job, and what work you like. Proceeding from this, it will be easier for you to decide whether you need to change your profession drastically (for example, from a teacher to a florist) or just a little bit away from the already prescribed direction.
With the first option, everything is clear: you will have to get a new education, finish some courses, etc. And in order to pay for this education and have a decent standard of living during the training period, you will still need to work with those who already work for you. Thus, for some time you will have to continue to do what you already know how to do, but do not want to. Cardinal change of profession is a long process. In addition, in the learning process you can be disappointed in the chosen course or education and start thinking about something third.
If you decide to move away from the direction rather than change the profession drastically, or if you just know that the work you are doing you do not like, but you do not know exactly what you might like, it's worth considering the related fields of your profession with other professions. Many work as if at the intersection of professions, go to receive additional education to be an expert in several more or less closely related areas. A journalist can try himself in advertising or copywriting, the sales manager becomes a client search manager, people with legal education often feel good in procurement or personnel management, hiring staff (same lawyers, for example).
The main problem of changing the profession is that many employers are still rather conservative: if a person has worked for five years in one sphere and suddenly turns sharply into another, even close, it can alert them. They will rather take a graduate with no work experience, but from a profile university, than a specialist with experience in another field, despite his quite appropriate knowledge and skills. Therefore, those who want to change their profession will have to work hard even to just get on the job interview: focus your resume on the skills that can be useful to you in your new profession, justify in the cover letter why you are interested in this particular area of activity, emphasize the willingness to learn and do not forget about skills, sometimes knowledge, but add weight to any specialist, for example, fluency in English.
Those who change the sphere of activity, albeit on a close one, should think about some additional education that gives at least basic knowledge. It can be courses, trainings, etc. The presence of even basic education is important for the employer, in addition, you will know better what you have to do.
