Clean slates

What would life be like if we were to always treat everyone we knew as if they had a clean slate every day? What would life be like if we treated our fears/insecurities/struggles as if they are being washed away on a daily basis?

To not remember past wrongs, grudges...

Once this quarter, I talked with a student (A) about another student (B). "A" told me that "B" knows his mistakes. I told "A" to tell "B" that we can have a new start and that I can forget the past (or something along those lines)...and, I think that recently "B" has been doing fine overall, attitude-wise...

Should I have this type of chat with another student (C) in that same class...? Ah, the drama that is human life...

Although it would be great if we could live our lives without remembering or keeping grudges about others' wrongdoings, how about in regard to our own guilt/fears/insecurities/ struggles/sin? We don't necessarily HAVE to be a certain way....right? Do we have to repeatedly encounter the same struggles? Perhaps it is very common, though, for people to struggle with the same sins for a long period of time...

Ideally, it could be nice if we could live each day with a new slate, in regard to our own sins, and in regard to not bitterly harboring others' sins...

Also, wouldn't it be nice if we didn't have to feel like we have the same fears?

I think my mom had the following experience, or something similar to it-- when climbing Mt. Lassen (maybe), a certain thought came to her mind -- something along the lines of making her think that she doesn't HAVE to be afraid of heights...

So..if people have fears of certain things (heights, cockroaches, etc.) one day, do they necessarily HAVE to have that fear the following day? Is it too simplistic to apply the 'every day is a new day' approach to one's fears?
