G-d's Calculations

I read a related idea to something I posted previously: here about how G-d has everything worked out based on our actions.  The idea can be read in its entirety as it appeared in Community magazine: here

The gist of it is, a sofer set aside some of his work time every month to voluntarily train two aspiring sofrim.  His colleagues said he was giving away valuable time in which he could be earning money.  He doesn't see it that way.  In his view, the time is well spent because it would otherwise be consumed by unpleasant things and he doesn't lose out at all.

According to his philosophy, if he is destined to lose work time every month, since this is part of life, he'd rather let his fellow Jews benefit from it.  "I am confident that these hours are lost time anyhow."

He and a colleague kept track of the time they spent working and the work time they ended up spending on other things.  The colleague was astonished to see that even with his volunteer work, the other sofer still worked more hours that month than he did, and that he lost time for various other reasons.

The conclusion: What is destined to be lost, one loses regardless, but you can utilize the loss of time for mitzvos and even save additional hours thereby!
