Yes, there is no way we can go back to the past and fix everything. What's gone, that's gone forever. What we can do is to do something now.
Now is the moment to do what you love, enjoy your life and work for what you want. Thank you @iamfreespirit for sharing this. Hope you will find my posts interesting as I found yours!
Thank you for your reply. I agree, we must move forward and enjoy life no matter what happened in the past.
