Act now!

One of my favourite quote is today's Quote of the day.

“Nobody can go back and start a new beginning, but anyone can start today and make a new ending.”

Yes, it is true to the core. It can be broken down simply as:
Don't live on the past. If you have committed a mistake and if you are regretting too much for that, then, your life is gone out of your hands. You aren't taking interest in your future.

All we must do is learn from the mistakes committed and try to not to repeat it. Just proceed the journey of life with your goal at sight.
Keep in mind: We must be looking forward for progress and not backwards.
