My kids do like to focus on one thing at a time. I know they get it from me. They want to finish whatever it is they are working on. It is just like me. They are stubborn. It can be good and it can be bad at times.
The house could be on fire, and they would want to finish a video game that they were using. They would have to get to the next level. Stubbornness can be a blessing or curse. There are times in which we need to listen to others and times when we have to go our own way.
The kids are determined to complete whatever they are working on. That can be great with most things. However, there is a time to walk away from something that does not serve you. Where you feel that you have completed something to the best of your ability.
