Some plants are tougher than others -so tough they survive against all odds in harsh environments like deserts. Take a look at desert plants in a group of photos that illustrate determination, resourcefulness, and endurance. Yes, I know that's anthropomorphizing, but it's still inspirational! Link

I mean, there are plenty more reasons to believe this is the case from psychology and physics. Humans are constantly imagining ourselves to be above everything else, even the lawful regularities that bind everything together (i.e. Physics). We have "decision-making processes" but this may not be fundamentally any different than a computer algorithm arriving at different results based on different inputs.
I think this is the time that someone steps forward and claims that we live in a non-deterministic Universe because quantum mechanics somehow proves there's randomization, or some such nonsense.
Though, I'm in agreement with you. Your phrasing was well done and quite artful.
