Adam Dietrich Ringle:
I ask these questions because non of my insights seem to hold weight to the drudgery of daily existence. There seems to be no escape from it, neither now nor in the future.
It seems you must be laboring under some false impressions and wrong views. Best to correct those first before arriving at any judgments about the efficacy of the Dhamma.
Right view involves a shift in how you perceive (act and re-act) to the reality that confronts you. It doesn't change the facts; the facts
are what they are. What changes is the depth of your perception about what it is that you think is occurring. This is difficult enough to explain until you arrive there and see for yourself. Then you will know.

Adam Dietrich Ringle:
I want to know why some people have so much confidence and understanding about things like nirvana.
What is your understanding of what
nibbana refers to? This is a good place to start if you want to discover an answer to your question.
