The irrational or rational mind compares the experiences of others as a measure for their own happiness when they feel that something is not right.
Going by what feels right works as long as there is positive reinforcement otherwise it will have a negative side effect on life. Some people aren't for example aware of choices others have made in their life because they don't focus on them, those choices lead them to happiness or better standing ground but for others, those choices that aren't in their control leading to a very negative event may disproportionately affect them and questioning.
You can't control for your initial years or childhood and That I think has the biggest impact on whether you will come across solving it.
It feels right to cry out in misery but rational or irrational mind would think it might be pointless if for however long you cry, no one comes to help or nothing improves.
I don't know what is considered rational or irrational thing to do given anything may seem rational for someone in specific circumstances and irrational for bystander. Is there such a thing as objective rationality that can be verified?
The older I get, the more I find that almost everyone battles through the questions of who they are and what they are doing with their lives. Most people question their values and purpose. I disagree wholeheartedly that content people don't ponder their lives. On the contrary, they are content because they are past that phase of life, and content because they are living a well-considered path. We are not deferring anything - we completed the process, made our choices, and are living them.
