Self appraisal is a necessary tool for the self aggrandizement of any individual. It is fine to at a point retrace your steps I an organisation, institution or group you find yourself. For there to be a successful self appraisal, there must be some set goals which will serve as a yardstick to measure your success or failure.
However, there is a rare situation where people do not appraisal themselves, and that will be in a rare situation that the person doesn't esteem whatever they needed to self appraisal. For instance, someone who joined the forum for fun or without a purpose has no reason to self appraise.
As a member of the forum and you're not growing in knowledge of the main purpose for which the forum was created for then it's a waste of time and energy for you. The forum is not just about earnings so if your growth in the forum is focused in ranks you are basically not growing.
There are people here who do not align with the purpose for which the group was created and they can still be successful. For instance, a designer may open a thread for great designs and earn handsomely from it. And we know that the purpose of the forum is not for designs, but then the designer is successful even without knowing much about bitcoin.
