Positive thinking can reduce stress levels

I came acsoss a great article regarding how you can change your life by positive thinking and i really get benefitted from this so you can also bring this into your life.

Research shows the benefits of optimism and a positive frame of mind are huge: optimists enjoy better health, stronger relationships, are more productive, and experience less stress, among other things. This is because optimists tend to take more risks, and blame external circumstances if they fail, maintaining a 'try again' mindset; this makes them more likely to succeed in the future, and less upset by failure in general. Pessimists, on the other hand, tend to blame themselves when things go wrong, becoming more reluctant to try again with each negative experience in life. They begin to look at positive events in their lives as 'flukes' that have nothing to do with them, and expect the worst. In this way, optimists and pessimists both create self-fulfilling prophecies.
When you understand this, it becomes more clear how optimism and positive self-talk can impact your stress levels, as can pessimism and negative self-talk. Negative events are less stressful when you see them as 'not your fault', and less likely to recur. Similarly, positive events are even sweeter when you see them as evidence of more to come, and see yourself as the master of your own fate. Additionally, because of the difference in behavior in optimists vs. pessimists, those who habitually practice positive thinking tend to experience more success, which can add up to a less stressful life.
Once you understand your current way of seeing things, you can make a conscious effort to look at things differently as you're presented with situations. So here are the ways you can be optimists:

When something positive happens in your life, stop to analyze your thought process for a moment. Are you giving yourself due credit for making it happen? Think of all the strengths you possess and ways you contributed, both directly and indirectly, to make this event occur. For example, if you aced a test, don’t just think of how great it is that you were prepared, but also think of how your intelligence and dedication played a role.

The key to optimism is to maximize your successes and minimize your failures.

It’s beneficial to look honestly at your shortcomings so you can work on them, but focusing on your strengths can never hurt.

Always remember that virtually any failure can be a learning experience, and an important step toward your next success.
