Stop being a prisoner of your past. Become the architect of your future.
As quoted from Robin Shama, this sums a stoic point of view, and the perfect resolution. Regretting what you’ve done or left undone wastes precious time, that should be spent on using what you’ve learned, leveraging your human assets, and making ambitious, but attainable goals. You’ll find before long the past will be your friend, and the future your promise.
