Ok, Mr literal. I am not talking about this:
"
Opportunism is the conscious policy and practice of taking selfish advantage of circumstances.[1]"
"
Human opportunism should not be confused with "seeking opportunities" as such, or "making use of opportunities when they arise". Opportunism refers rather to a specific way of responding to opportunities, which involves the element of self-interestedness plus disregard for relevant (ethical) principles, or for intended or previously agreed goals, or for the shared concerns of a group.[3]"

I think you know that though.
