My doctor tells me that there is some theories that ADHD may be an evolutionary response to dangers in our environment. (like avoiding lions or being alerted to changes in weather) When I think about it this way I feel better about rejecting medications (or accepting them). Personally just understanding the pros/cons of ADHD has helped me identify some of my shortcomings. For example, I can focus for days on the wrong topic, so I need to be aware of this so I don't work on something unimportant and then get burned out. When I don't know the right thing to work on and break it into concrete steps I find myself unable to accomplish anything at all for days or weeks jumping from task to task every 5 mins.

So I suggest you explore this to learn about yourself so that you can take the newfound information to make the best steps toward your personal/career/etc goals. That may be disregarding everything they suggest and refusing treatment, but understanding more about yourself and how your mind works cant be a bad thing can it?
