P.S.

Pat pat to myself.

It is okay to make mistake. Nothing goes in vain even when it seems that so much had been lost and regretted. At the very least, you got to be more understanding to others who probably did the same mistakes (especially this kind of seemingly silly and worthless mistake) and later on could give your shoulder to those in need. Life does not come with manual, so it is fine to make mistakes. All the more when you usually still keep making mistakes even when instruction is very straightforward. We are only human, it's just that.

Hm, actually life does come with manual. It's all in the Scripture, the Living Word.

Nothing to despair, the Manual says there is always chance to start again and everything is going to be alright.

Carry on carry on.
