How to change a profession
Think about it: what do you dislike about your old job, and what kind of work you like. On this basis, it will be easier to determine whether you need to change the profession dramatically (for example, teachers at the florist) or just a little away from the already given direction.
With the first option everything is clear: we'll have to get a new education, finishing any courses etc. And to pay for this education and have a decent standard of living during the training period, we have to work on what you already working. Thus, some time will have to continue to do what you already can do, but don't want to. A radical change of profession is a long process. In addition, the learning process, you may be disappointed in your chosen course or education and start thinking about something third.
If you would rather move away from the given direction, than to change the profession dramatically, or if you just know that the work you are doing, you don't like, but don't know exactly what you would like, you should think about related fields of your profession with other professions. Many work on the joint professions are going to get additional education to be an expert in several more or less related fields. A journalist can try yourself in advertising or copywriting, the sales Manager become a Manager in search of customers, people with a legal background often feel good in purchasing or HR, the hiring of personnel (the same lawyers, for example).
The main problem with the career is that many employers are still rather conservative: if the person he worked for five years in one area and suddenly moves to another, even loved one, it may tip them off. They would rather take a graduate without experience, but the profile of the University than of a specialist with experience in another area, despite its quite suitable knowledge and skills. So someone who wants to change the profession, will have to work hard even just to get an interview: focus your resume precisely on those skills that may be useful to you in your new profession, justify in the cover letter why you are interested in this field of activity, emphasize willingness to learn and don't forget, albeit sometimes minor, skills and knowledge, but adds the weight of any specialist, for example, proficiency in the English language.
Those who change their field of activity, even in close, you should think about some additional education, offering at least a basic knowledge. It can be courses, trainings, etc. the Presence of even a basic education is important for the employer, in addition, you will better know what you are doing.
