I feel past can't be ignored as it'll haunt but when one accepts past no matter what happened, then the person will have more mental strength to face things
So, When one is ready to face consequences without getting Emotionally affected will be more happy but its tough
This can be achieved when the person understands some are inevitable and can't change them
Instead of worrying or Overthinking keep your guards on, be ready to face things, don't succumb, live in reality
Don't always hope for miracles to happen INSTEAD be a MIRACLE!
