I didn't read that from Brian earlier, and I would agree completely. These are all very good things to implement into your day/week that can lead to being productive, not feeling overwhelmed, and preventing discouragement as often as possible. I know I have said a lot, but I want to add one more suggestion..........
Don't do what the modern school setting does. Don't focus on what you are good at while ignoring or pushing away the things you struggle with. You know what you do well and don't need help with that. Make sure to emphasize that which you find difficult and work at it. It will be tiresome and discouraging at times. However, when you master it, think how much more rewarding it will be.
Try a few exercises for me and see if they help.
1. Eat, brush your hair or teeth, and drive with the opposite hand that you are used to using.
2. Drive an alternate route to work as often as possible from memory.
3. Write down a list of things you need from the store. Find a cool, stupid, or silly way to remember the list. Then shop from memory.
All of these things are small tasks, but require you to do it in a way you are not accustomed. If you can do this, you can do anything. I convinced one guy to try things my way by asking him to write a passage for me. I told him to write it with his opposite hand legibly and I would give him $100. He looked at me like I was crazy and said, "that is too hard!" I just looked at him and said, "yes, but I can teach you how to do it." That same thing can happen for anyone with ADD, ADHD, or anything else from dyslexia to dysgraphia or autism.
