I think I've figured out my issue. I had to actually sit back and analyze the entire situation, which I should have done before creating this thread.
Here's the deal: I'm getting the results I want, so far. I'm profitable and I have a system that is working for me. My thought process at the time was that if I could put more work into the markets, I could get greater returns. But I now see that such thinking doesn't make sense and could actually cloud judgment.
Currently, I'll spend 30 minutes to an hour getting the latest news from around the world, then I'll spend a couple of hours analyzing charts and looking for specific trade setups that I like. So far, that system has been profitable.
Lesson learned here: if it works, stick with it!
