The successful person is who takes a calculated risk in his life. But do not rush. Jobs Do not change job unless you have another one in your hand. Usually married people are more cautious in changing jobs. Also people in their forties are more cautious than those in their thirties or twenties.
Studies shows that changing jobs is one of the main resolution that people have.
Studies also showed that no one is happy at his own job from the porter to the chairman of a corporation. My advice to you is to study all the dimensions of changing your job this year. Send your resume. Do not give out your birth date. This is the most serious decision that you take in your life.
