Past is gone for ever. Today is all that we have at hand to work with. Future is unknown and in dark territory or uncharted waters, what ever you would like to call it.
We have no control over the past , but some over the present and the future to a certain extent. We can't change the past but we can change the future. It is in our hands and entirely up to us to create our own path. We cannot blame our parents or anyone for any current difficult situation we are in. We got ourselves in and it is our responsibility to get ourselves out of any difficult situation we are in. Nothing lasts for ever. Neither good or bad times. So we always will get a second chance to correct ourselves and take the right path. If there is no path, create it.
