The stage when the heart learns to let go of attachments that colour the ability to decide is the stage where life can look forward to a change much yearned, but never attempted to achieve.
The future is shaped by the present. The present cannot ignore the past. Past is history, meant only for reference. A better future can happen if the present learns from the mistakes of the past.

Very deep thought, put very nicely in words. We all need to change something or the other but we never attempt.
Thank you Basit!
