Developing a Positive attitude

To have a positive attitude means to see the good part of your situation.Having a positive attitude matters in everyone's life and specially in people who are too sensitive or those who get too concerned about something.
It is important from even the small thing like getting less marks and developing a good attitude to a large situation like saving a persons life. For instance, suppose a person decides to commit suicide due to a particular situation, if he/she develops a positive attitude towards the particular circumstance, then he might recede from suiciding which is a great action, which shows it has a role to play in preserving lives too.
Now, this does not mean that you don't take a serious situation seriously by just thinking its ok ,lets see the positive side of it. Then you will end up in neither getting concerned nor seeing the assertive side of it.
Therefore by just seeing the good side of every situation but at the same time being careful not to repeat it, one can do great things in life.
