i know how you feel. Sometimes you just get lost in conversation, lost interest in it completely, and forgot what the other party has just said within seconds.

Studying is no better. Your friends complained they cannot study for more than 1 hour a day, but you cannot even stand 3 minutes reading. Its not that you cant read, its just that reading became a secondary activity in your brain, with something else in focus.

Its difficult to finish one task at a time, because you will want to do another thing after a few minutes working on something. It gets irritating when by the end of the day, you accomplished nothing. You know youre doing it wrong, but its hard not to feel bored.

I noticed it gets much worse if Im tired. Ginkgo, those chicken oil dont work shyt for me, but try to keep your mood elevated, your brain will concentrate much better when youre psyched up on what youre doing. Also, get a colleague who understands you to help you motivate yourself and monitor your work.
