Learn to separate the troubles and difficulties of professional activity (not fulfilled the plan on time, did not reach the necessary financial and other indicators.) From his personal life. Do not worry because of problems at work, in which you are not to blame.
If the office has some annoying factor that affects your mood (annoying colleague, bad computer, inadequate lighting), it is not necessary every day to endure the inconvenience - solve the problem as soon as possible.
Difficulty office activities often lies in the fact that you can not choose the people you work with. If the relationship with colleagues do not add up, do everything possible to establish them: try not to criticize other employees, even if they deserve it, do not spread rumors, do not waste time on empty conversations with windbags.
You can not love your company, but their responsibilities should always perform in good faith. When you are working well and see the results of own activity, you are much easier to move on. Get enough experience and expertise, you can always find yourself another job.
