Having a sense of purpose in life goes a long way to helping you feel confident, secure and happy. A sense of purpose can be brought about by anything in life: it can be related to your career, bringing up a family or doing voluntary work. It is all about fitting in and feeling you are making a difference in life, that you are achieving something and getting somewhere.
If you have a sense of purpose in life, you have something to look forward to everyday, a reason for getting up out of bed in the morning with a smile, it makes you feel good on the outside and so good on the inside. It leads to a more confident person who is happy with their position in life.
Younger people very often have no problem developing a purpose in life, they are just starting out and the majority of them have exams to pass, careers to start building, meeting the opposite sex, dating, marrying and eventually starting their own families. The majority of the younger generation has a lot to look forward to and so have a sense of purpose in life.
However the older we get, uncertainty can set in and we can start wondering about our purpose in life. Perhaps the children have grown up and are no longer dependent on you. Relationships break up or we reach retirement age and no longer have our work as a purpose in life.
