"Never give up on the things you can change, and learn to live at peace with the thing you can't"

Memory in terms of information retrevial (ex: memorizing digits of pi) can be learned.

However, trigger-based memory ("when I get home I should do X", "before I leave I should do Y", etc), is usually not something that can be learned or improved and I think its really counter productive to "just try harder". Unless you're in a pretty tight situation though (like gov work where you can't record or write down the info, or fast-paced work like waiter/waitress work where theres no time to record/revie), there's usually a way to work around a deficiency in trigger based memory.

Sometimes we can be in the wrong bussiness, but usually its a matter of support systems.

More often its wrong bussiness because they dont let us setup "unusual" and "shouldnt-be-necessary" support systems
