I would like to think of the Divine. Saints say that we are affected by the final things we think about. So if we are attached, for example, we will think of the attachments: family, house, friends, money ...if we are Godly, we will think of God.
So my final good deed would not be worldly, I would wish to think of God and use all my energy in this direction. After all, if I did't please him in life, then I doubt I'll be able to think of Him then, let alone other good deeds.
So I wish to think of Him in order to unite with Him, to make my passage smoother, so to speak.
