Past Present

I’ve been told I use past situations and past experiences with people too much in how I assess new situations and people. And since situations and people are different, hence my assessments and their conclusions will be wrong.

But isn’t that the basis of learning from the past?

Isn’t that how we all move forward and consider current/future situations, based on the inherently accumulated knowledge and experiences we pick up or are exposed to along the way?

I think though that I must have misunderstood.
