I once heard world renowned motivational speaker Les Brown say that most people experienced their first heart attack on Monday morning. That is because most people are not happy with their jobs. While there are thousands complaining of joblessness, those with the jobs (and sometimes high paying jobs) are complaining about not being “fulfilled.” 
If you are not “happy” with your current job, change it. If you don’t think you can change it, quit complaining and start increasing your productivity. All the energy that you spend complaining about being unhappy can power a city with a few thousand people for days, even weeks depending on how bad your “I hate my job” case is.
On a more serious note, read the book “Life is Tremendous” by Charlie Tremendous Jones.” I promise you if you read that book with an open mind and an open heart, your whole attitude towards your job will change. You can place the order for the book on this page: http://goo.gl/klV4GJ. I read the book in two sittings and it had been a while that I had read any book in less than five sittings. Get that book!
As you wait for the book to be delivered to your mailbox, answer the question: Why was I hired in this organization? Maybe you don’t like your job anymore because the problem you were hired to solve has been solved and you have not had anything challenging to keep you excited about working there. Discuss with your supervisor or your manager how you can modify your daily activities to doing things that are more exciting, more engaging. It is possible for you to get the fire burning again. Answer this question at the start of every work day: Why am I on the payroll? The day you cannot give an answer satisfactory to you and the people you account to, move on!
Why are you on the payroll?
