No burn. Only deliberate curiosity. If you take this approach, and keep your expectations in check, you do not make yourself vulnerable at all. I keep my eyeballs peeled when I am out of doors anyway, always. If I spot something that fits my understanding of what this animal is, I will have chalked up another experience of the kind I hope to have plenty of by the time I croak. If I don't, I'll still have lots to reflect on that is pretty special too. I think we call this outcome a "win-win", am I right?
No timetable. Low expectations. Look for consistencies in the evidence and follow it. Do that, and you're playing the long, smart game, I believe. I"m astounded at all the mind-blowing discoveries that have been made in my short life. None (Repeat: NONE) of those were my due, or anyone else's. They could just have easily not happened. I'm just grateful to my fellow humans that they expended the calories to make them, or were paying attention when those were dropped in their laps, and had the presence to document them when they did. I'm thankful for all those adults and teachers who steered me right as a kid to pay attention to that kind of knowledge, and who stoked my energy to stay curious, to this day. Life would be a pretty grim undertaking without that... for me at least.
I try to find a down-side to this field of inquiry, and I'm frankly unable to ever see any.
