There seems to be certain things that I just cannot learn now matter how many times they sting me. For example every time it rains I walk down 5 flights of stairs only to realize that I didn't pick up my umbrella. Even though I thought "don't forget your umbrella" literally 2 minutes before leaving.
Although you will find contention to this statement in quite a few places, I was taught during my PhD work that the subconscious mind doesn't process negatives. This is why hypnotic suggestions and affirmations should always be couched in the positive (MADD has now adopted "Drive Sober" as their motto instead of "Don't Drive and Drive" for this very reason).
Basically, you've actually been programming your subconscious mind to forget your umbrella - and you do! Try this simple re-framing instead: "Remember to take my umbrella" that's the positive version for what you're trying to accomplish.
