Pity is nary a friend you want to invite, nor an acquaintance you would accompany.

Those who act like a rug invite being walked all over.

Trouble never turns down an invitation.

One cannot strategize for a hand that has yet to be dealt.

What you'd have done do; what not delegate.

Concerning days on which to rest, Sundays are rather apt. Other good days are Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday.
