Starcommander, Aug 6, 2019 : Yesterday was a cancelled cheque, tomorrow is a promissory note, but today is the cash you have, so spend it wisely. This means that what is gone is gone. Past cannot be changed. Stop regretting it. Dont over think about future you may never know what may come. Do the right things in the present irrespective of past or future. Believe me this hit me hard 10 years ago..
