There is something that many people fail to understand about Attention-Deficit/Hyperactivity Disorder (ADHD). In adults, this condition would be assumed to be easy to deal with. What people do not know is that adults are aware of what they need to do about it. It is only that the nature of the condition inhibits them from executing what they wish to go into action. The adult adhd test stops you from doing what you would love to do, and thus not realizing success in the exercise.
There are medications you can take to help deal with the symptoms of adhd. Those, however, do not produce progressive actions in you. You will not start being organized, managing your time well, and avoiding instances of procrastination. A method that is so far showing promises of success, with a few examples of effectiveness is cognitive behavior therapy (CBT). Adults tend to feel the effects of this condition more profoundly. The longer one waits to address it, the harder it becomes to get away from its clutch. The situation will leave you in a state where you are so hard on yourself, and with little hope for the future. This only serves to compound the situation.
CBT can be applied to help get insights into how ADHD affects your disposition and intentions. You will be helped to move from the mindset of exerting a lot of effort to overcome your weaknesses to looking at that weakness objectively, and taking time to understand it for what it is. Once you can view it as such, getting away from its grasp shall be a more achievable goal.
One major symptom of ADHD is procrastination. Procrastination shall show itself up when you have a task to complete, but somehow end up not doing so. You will instead do a number of other things that at that time seem important but in hindsight, were only there to distract you from what you knew you ought to have done. ADHD puts it in your mind that what you needed to do was going to be tricky, miserable, or simply too hard. With such a mentality, you shall look for other seemingly important yet easier things to do, and keep yourself busy, as time goes. You may completely forget about the main task, or conveniently remember it when the time remaining is realistically too little. The decision that what you need to do is too much and finding something else to do happens so fast, you would barely notice the transition.
With CBT, you shall be able to slow that process down, examine it critically, and find better ways of taking control of the situation and steering yourself in the right direction. Read this article about ADHD: https://en.wikipedia.org/wiki/Attention_deficit_hyperactivity_disorder#Signs_and_symptoms
