True indeed!!! Sometimes we just forget that it's just a guide. We become confined in our thinking. Another mistake is to think just because it means so much to us that it has to mean the same thing to other people. If they disagree, we assume they're "denying the truth."
Doctrine assumes everyone has the same needs, or that everyone will reach the same conclusions if given the time -- that over time they will see things our way. But hey -- we all come from different walks of life, so we can't presume people have to think the same way as us. Also, our thinking changes over time as we discover that certain things are more important than others.
As we get older, accumulate life experiences and/or see more of the world, we often find our earlier attitudes or beliefs to be either wrong or misguided. We find new ways of seeing things. That's why sometimes doing as we're told isn't necessarily a good idea. We should instead focus more on affirmative experiences that either reinforce existing beliefs/convictions or lead to new ways of seeing things.
