My profession is an accountant and economist.  My job is very important.  I help the company to keep records of all the business operations.  I also do a lot of forecasting by making calculations for future transactions.  My boss often asks me for advice.  I help him with economic issues and business planning.  My job requires a lot of attention and good skills.  I also take part in company business meetings and speak about our results, problems and prospects.  I always read special economic journals to keep up with the changing economic legislation.  I am very happy to have this job because I like it.
