alarming to the senses

how do we ever really know what is good for us? What is authentic and really sustains us or whether or not it's just there for security and assurance. How is anything really ever known and why do we find ourselves questioning it? The standard for anything in life such as love, happiness or success are not measurable by scale but predetermined by others standards or experience. So how is truth for any of these things really ever consequently known for relevancy? Security is really what keeps us 'stable' and hopeful in what we think is sure and truth and all that we put into those mindsets. So what to do when you find yourself constantly questioning everything in life? Never stop questioning,challenging anything and everything is the only way to fully experience and gain from.
