As someone who struggles with ADHD, staying focused is incredibly difficult. I tend to say I have the attention span of a gnat...and if you are familiar with the south, those tiny things buzz around like crazy trying to annoy you.
The thing is, when you have a dream, and you're actively chasing it, staying focused becomes even more difficult. You're trying to get your normal things done, while also trying to stay focused on what you're chasing. Life simply gets in the way.
My point being, don't let anything stand in your way of chasing your dreams - no matter what those distractions are! It's okay to tell someone 'no' in order to get what YOU need. Don't let the world distract you. Keep your focus on your goal! Keep your head down and your eyes firmly focused on that dream and before you know it, it'll be at your fingertips!
