Obviously in extreme cases there are exceptions however:

When interacting with someone do not look at them with tunnel vision see the whole person, the whole picture in actuality and in potential

Then
If there is something that was said that you find hard to get past or get over despite your best efforts

If there is something that was done that you cannot change

If you are stuck somewhere in some issue etc

Be wary of and honest about your own fallibility and then with humility

Stop...step back

And learn to build a bridge over that which has been done and cannot be changed specifically and in general in order to preserve important relationships move on and go forward to live your greatest life as the constantly best version of you that G-D allows you to present to the world at any one time
