How good is your short and longterm memory?

When someone tells me what i have to do, i have to write things down in order to not forget it. Sometimes i can remember - but most of the time the task/sentence just disappears.

Also when somebody asks me if i know thing x , which happened 1 month ago, i have to think about it a long time :/

I would love to travel and work somewhere else, but i am afraid to forget all the instructions they tell me or get lost haha
