I don't know. Slightly you sound like you have ADHD.

Stimulants medications for ADHD like Ritalin and Dexamphetamine tend to increase drive and motivation. They MIGHT help you, as long as you are not prone to anxiety or paranoia.

A very careful, non-excessive dose of the above psychostimulants, could provide you the boost you need. However you must ALWAYS have decided the dose you will take a day in advance, and you must be very careful not to abuse such substances. A psychiatrist might prescribe a low to mediium dose for you, but you should read up detailed information on side effects (don't be alarmed, just be aware)
