Take a moment relax yourself and then take a fresh start. Whenever you feel you're exhausted and you can't take it any more, ASK.Yes, it makes some difference to your state of mind. As you ask something you get to know that what you have asked is totally your question and you're more concerned about what others would be thinking about your question. This is your state of mind.
You should ask to know,not to show what you know. What happens when you ask something?
Your concentration level increases, you grasp things easier than you did sitting idle just because its your question.
Make it a habit, whenever you feel you just don't understand the thing SHOOT. Don't just care about what others will think about your question ,you should be proud that now you're going to learn more, grasp more and listen more. Let your question be as absurd as '' Is Apple a fruit?''. Just don't care about the question, feel good because now you know more than you did earlier.
