Don't just look at a bad idea and throw it away. Yes, it should be discarded, but if you have a bowl of 90% bad, moldy cherries, and 10% that haven't even touched the mold, fine to eat, why throw the whole bowl away?
People too often look at a bad idea and don't even think twice about tossing it. Especially before anyone else can see it. They're too embarrassed for anyone else to see it.
One thing you learn being poor is DON'T WASTE FOOD.
As an artist, you learn similar things about DON'T WASTE CREATIVITY!
Maybe your bad idea didn't come from creativity, it came from your own flawed imagination. But that doesn't mean your creativity can't play with it and come up with some really good ideas from it.
Throwing away a bad idea too soon is just asking for more bad ideas. You came up with that bad idea because your mind was in that mode. Finish it. Give that "negative vibe" some exercise, and pump it out til it's drained away. By that, I mean, don't throw the bad idea away, flesh it out as if it was a GOOD idea. It's like stretching your arms in order to get the cricks and cramps out of them. Eventually, as you mold the bad idea around, all that negative stuff will be unknotted, and you'll start having good ideas again.
That's the 10% you don't throw away. Get rid of the other, moldy ideas. Keep the gold.
Just about every great idea through history was built on horrific prototypes. Just watch the pilot episodes for some shows. They can be so bad, you can't believe anyone wanted to make it a real show. And it went on to be amazing, with proper changes before episode one, that is.
(No, not every pilot episode is awful, but I've seen some doozies that later became hit shows)
Sometimes you'll have several REALLY bad ideas before coming up with anything decent. And that 'something decent' is just another "not so great" idea from which you'll squeeze something better later on.
I remember when I wanted to put footnotes into Teen Titan things for fun, so I was going to make a stupid self-insert just for some laughs. Making the outfit for that OC was an unusually grueling process for me. But rather than just throw away each bad idea halfway through, I felt it out more. Finished numerous "bad ideas" (some VERY bad) just to see how it looked, and if I could take anything good away from it. Looking for that 10%. Trying to exercise that negative flow from my mind.
Some of these are cute looking, but NONE of them fit. Not if it was going to be "me." Making them all bad ideas, no matter how they might look on someone else.
These ideas are all now in my "discard" bin. I may find a use for them someday, but for now they're just random outfits that I came up with once. On a laundry day where I was bored to tears and had nothing else to do. XD
I also remember a time when a former friend of mine kept sending me "ideas" on how he'd like to make a season 6 of Teen Titans. I say "former friend" because he didn't understand the creative process and refused to even talk about editing any of his ideas. Eventually, he blew up on me, dropped it all in my lap out of the blue, and left the group.
I tried to explain to him, after one of his ideas flopped "no, no, man... look at it this way--we got some great OTHER ideas, from that one bad one! These are awesome ideas! It's just that the first one was a dud... that's the way it always is."
He didn't want to hear anything positive about calling his idea "bad."
Some people sew their egoes to their ideas and can't face it when they're no good. It means tearing it off themselves, a painful process to them.
You can't argue with them either, even in a nice way. Don't bother. Just try not to be like them.
You have no idea what kind of muse you're throwing away. Even if the only good thing would be to make fun of the bad idea for laughs, that's still SOMETHING good.
