I find that I get distracted really easily when I'm working on my project. I don't know if it's my ADHD or something, but my mind seems to wander a lot whenever I'm working on anything. It's a blessing and a curse. On the one hand, many of my best ideas come to me when I let my mind wander, but when it comes to implement them I have a hard time focusing on the task at hand.
Yes, it's true wandering is both bless and curse. In my experience, making a good schedule and each today's goal is the best effective thing to reduce wandering's side effects. Good luck to your work or study!
