Healthy Mind is everything. It reflects who you are and will make sure you see so much good things around you. To put it, even more, simpler, let's just say
Good Mind and Good Health go hand in hand.
The more your mind is in peace the more productive you become.
A Healthy mind Forgives : It Forgives others and sometimes 'itself' too. Forgetting is secondary, but to Forgive is something that's never easy and that's what makes the mind more stronger and healthier.
You cannot be Right all the time: Accept when the wrong is pointed out to you. If your mind still feels "No, I'm Right" or "Gets defensive in accepting your mistakes" then retrospect yourself. Healthy Mind will take-in, understand and analyze the wrong it did and will look for solutions.
A good mind needs to let go of things: Sometimes things go out-of-control and there's nothing you could've done. So, Let it go. Guilt shadows the "next right thing" to be done.
To top it all, always remember this wonderful words:
I will never let anyone walk through my mind with their dirty feet - MK Gandhi
The weak can never forgive. Forgiveness is the attribute of the strong - MK Gandhi
