Think this is what I'm after.
OK, so try this (I had what I think is a very similar problem to the one you describe).
Think about whatever fact is
most important to you. To give you an example, I trade using PA. Most people think of candles and the rest, but actually in my opinion location is the most important thing. Now location is just what we call it because we approach things visually, but really a "location" is in fact just a price or a range of prices.
To my mind (again, this is just the way I see it) large round numbers have huge significance. Now, when I'm trading intraday Forex, the sine qua non is that price must be at a round number. This gives all the benefits that you're speaking about, and makes scanning charts very quick and simple (if there is no trade, about 2 or 3 minutes in each hour to watch 29 pairs). This filter keeps me out of loads of bad trades, and gives me an opportunity to save myself or at least cut my loss on the bad ones that I do take.
Then your psychology and discipline come in. If you adopt this approach, you'll doubtless see a ton of trades that work out not at big round numbers (or whatever your thing happens to be). Of course, the ones that don't won't stand out quite so much, you start deviating from the plan, and we all know where that ends. But hopefully, the mere fact of having a line in the sand should help with discipline - it gives you a clear rule that you do
not break.
Look at the chart I posted on the recent gold thread. With one line and one bar you could have sold gold just below its all time high. Just that - two factors to catch gold at its peak.
Here's the pi$$er. You talk about information overload and all the rest, and we probably all know what it's like to get analysis paralysis. Go back to discipline, confidence, psychology etc. I was watching gold because 1250 is one of my big numbers, and there is a very good chance you'll get a reaction here. Up, down, we don't know yet. Some really nice PA came along telling me to go short. But I didn't because I deviated from my system. I thought "Am I trying to pick the top? Everyone knows you shouldn't do that" and all the rest of that conventional wisdom bullsh1t. Now go and have a look at gold and see the move I missed through being an a$$hole.
To some extent you can "automate" your discretionary trading, so to speak. No stress, no fuss, you see the set up and pull the trigger.
Hope this helps, but happy to try again if I've missed the point of what you're asking.
