In a research, it was found that only four out of every five employees were happy at work. Surprisingly, it wasn’t the salary or the love for the work that made people happy. In stead friendly, supportive colleagues and a good manager have been found to be the primary causes of happiness at work. So how do you keep your spirits up and develop a sense of joy on the job? Here is some advice.
Happiness is a state of mind, and though not many people realize it, staying happy at work is totally based on a positive attitude towards your job. Concentrating(集中注意力) on the bright side of the work rather than keeping talking about what makes you unhappy is the basic key to happiness.
Challenge yourself and take charge of your own growth professionally. Boredom is one of the primary reasons that cause people to change jobs. To avoid feeling bored, you can find new challenges and it’s a great feeling to take control over what you do and see a task through.
Complete our tasks, however disagreeable or tough they might be. This gives you an individual(单个的，特别的) sense of achievement and encourages you to work towards your goals in future. Also keep learning and gaining new insights while at work.
Sitting and staring at your screen all day long isn’t going to help you. Instead take breaks and go outside for some time. They don’t necessarily have to be long breaks but staying out for a few minutes to feel the gentle wind can keep you happy. Eat your lunch out side or walk for a few minutes during that hour, which helps you stay happy at work.
