Yep, it would have helped a lot. Back when I was in university, we did not even had a single note-taking/research course. We had to figure it out by ourselves, which i know a lot of my fellow students did not bother doing.
As for Obsidian, do not hesitate to share a few insights as I have yet to see how it can help me better than paper does. I mean, beside a faster search inside my notes (which is not what matters the most to me). For example, the fact I cannot manually/freely reorder my notes, in a note-taking app, is beyond me and it’s something I do all the time with my slip of papers. But I’m also willing to admit I’m missing out on something important.
Imho, a better question to ask yourself would be to consider why you’re giving up quickly?
If you give up because you realize you can’t be bothered with whatever that activity is, fine. I tried a few things I realized had little value to me. No big deal.
If it’s because you don’t want to make the effort of learning to do it properly and/or because you can’t accept that, as beginner at it, your not already good and get not success. Then, it’s probably not a great decision.
I see two things our society as a whole (even more so when it is lived through social media lenses) tend to discourage younger people to reflect upon:
It is to be expected from most beginners. That’s why as adults we’re supposed to teach ourselves (so we learn and get better at that thing), and that’s why, as little kids, we are being taught by adults. And that learning takes time and practice. A lot of both.
Failing is how we learn. Remember how you learned to walk as a toddler? Was it by being good at walking? Or was it by falling on your diapered bum many, many times over and over again like a clumsy toddler? At least, that’s how I learned ;)
That’s also how we learn to read and to write. By doing mistakes. Not by picking up our first pen and writing the next best-seller.
So, to get back to your question, if you give up on something because you would want to be good at it instantly, you’re probably missing out on something.
