It can be a challenge for me to stay focused at times. I have ADHD and often find it a struggle to focus on just one thing.
For me to able to actually focus I must first keep still enough to let my brain think. This means I may fidget or doodle. This sometimes causes people to think I’m not listening. This caused a lot of problems in schools when teachers expected me to sit perfectly still and look at them. I am less likely to listen when I must do that because I’m concentrating on staying still.
Sticking with a task from start to finish is also difficult for me. Sometimes I can complete a task but many times I get distracted. One trick I use is to set a timer for 15, 20, or 30 minutes etc. When the timer goes off I do something else for a while. While not being able to stay on task often caused problems during my school days, it has been a plus in many jobs. There are times that multi-tasking is necessary.
Staying focused in life and remembering what must be done is at time a daunting task. I’m organizationally challenged. One of the tools that I use to keep myself organized is Outlook.
