I have a bad memory problem, and I'm 22 years old. Should I take Ginkgo biloba?

I work at a web marketing and design firm and I also freelance. My memory and concentration has been my main weakness since I was 10 years old and it's bothering me today.

I have post its all on my monitor and keyboard telling me things not to do like "Let people know when you are done with a task" or "Always backup, Never Overwrite"..

Then today I messed up on both of those and it cost me time and a worst rep in the office. How can I concentrate better and remember better on things. I use the "Getting Things Done" methods by David Allen so I can empty out all my tasks into my moleskine, but I stress a lot and I do go to psychological therapy once a week.

Should I take Ginkgo biloba?

Any help is great, thanks!
