Yesterday, Today, Tomorrow - What does they stand for U?

I think Yesterday is the past so we should forget what ever happens and tommorow we dont know what will happen whether we will be alive or not and today is the present and we should enjoy a lot

I usually don't think about yesterdays. I think only of todays and tomorrow. Anyway my yesterdays were far much better and I am so happy to enjoy my life. But today I am better a lot than yesterday. I hope not to go bad when tomorrow comes. Because none can say what will happen in future. So let's hope good will come for everyone of us. Thank you for making such a discussion.
