This showed up on the GWJ forum, and it is going to be my mantra for the next two weeks:
I must not Steam Sale.
Steam Sale is the wallet-killer.
Steam Sale is the little-spending that brings total budget obliteration.
I will face the Steam Sale.
I will permit it to pass over me and through me.
And when it has gone past I will turn my browser to see its path.
Where the Steam Sale has gone there will be a hundred Steam games from past sales I’ve yet to play.
Only this time my finances will remain.
