Problem I see is the fact, that once we're getting older - we may end up moving away from our "true-self"

You're very correct - because our job, family and kids most times take our focus from ourselves. That's why I really suggest that people should take out time, to discover themselves in their early stage of life, and know what will make them have a fulfilled life. In order to really avoid a situation of turning into an old grumpy person who never followed his/her dreams - we should do all we can to know ourselves, and the sooner, the better. Thanks for coming around!
