I don’t indulge in this kind of thing often but if I, at my current elder age, could recommend something to myself at a younger age, I would say: be more willing to do what you want, follow your instincts, follow your heart - not only in what you do but how you do it and when you do it and where you do it. You’ll get where you need to be in the end.
As a beginner, I find it easier to focus on one category and it helps me to organize.
That’s the the thing. Each of us are different in how we learn, process, organize, etc. This site is a powerful tool but, at its heart…
iNaturalist describes itself as “an online social network of people sharing biodiversity information to help each other learn about nature”, with its primary goal being to connect people to nature.
For me, I use it to access joy. I get lots of other stuff from it, too. I’ve increased my knowledge base in all sorts of directions. I’ve become more passionate about saving regional areas of natural habitats. I’ve made friends. I’ve found solace walking in nature while the world (sometimes literally) burns around me.
But, at the heart of it, I access joy. And I let that drive me.
If focusing on one area fits your learning/organizational style, why not allow yourself the comfort of that? I would predict that, as you move around your comfort area and areas of interest, you’ll find that those areas will expand. And it will be joyful moments (‘who knew that ladybugs lay eggs on stalks!’). Approaching an endeavor with some set of proscribed expectations kind of sucks the joy out of it for me. But then, I’m retired and I’ve reached a point where I can say and truly believe (for the most part) ‘I don’t have to do anything I don’t want to’ and I run with that.
It’s been a tough world out there the last few years but, in this way, I’ve never been happier.
Follow your heart. :-)
