Great quote @greatpath sir, i think It means Learn from the mistakes you made yesterday, as so you will not make them again. As for today, just live. Don't worry about what has happened, or what will, just live your life. Hope for the best to come in later days. Hope good things will happen tomorrow, and days to come. Just don't stop asking questions. Asking questions is the way you learn. If you stop asking, you stop learning.
