Doing this by yourself is pretty much impossible, since you can't make your charactere come up with ideas you don't come up with myself. In my experienced, it worked quite okay to rely on a little subtle help from the Master or hints from your group of players. Unfortunately this little "out of game" experiences might annoy you if you rather keep the atmosphere up.

In my case, I played a wizard (of sorts. I'mfrom Germany where we got our own D&D ripoff named "Das Schwarze Auge" ("the black eye")) and he's able to make prophecies, so the master can slip him hints every once in a while, which makes my character able to come up with ideas I wouldn't have thought of all by myself.
