Have you tried using post-its? These are notes you can stick up places you frequent, like your work computer, your fridge, mirror, or other conspicuous place. If you keep on forgetting what you wrote, it's effective to use a post-it and place it in places I hereinabove mentioned. Or you can try place a task or to-do note in your mobile phone and place an alarm for each to help you recall.
I hope that helps!
