Do not mistake my online personality for my real world attributes.
Such as using the carry capacity tables in the PHB I have a 14 Strength and since I do have a pretty mean shot with a weapons at range and able to dodge things quite easily, I would also give myself a 12 to 14 dex. Constitution would be a 10. I have had my share of illnesses and I am out of shape. College educated and did quite well in my classes so that garners a 14. I can be rather impulsive so an 8 in Wisdom. As for Charisma I can be quite friendly and persuasive if I wish to be, but only in the real world dealing with people face to face. On the net I feel I can be more free to vent my irrationalities. Overall a 12 Charisma for I am very well liked among my peers.
Now one would probably scoff at writing oneself as a DnD character but it can be quite fun actually. I did a whole Forgotten Realms campaign where the players made themselves as PCs trapped on Faerun, using the Curse of the Azure Bonds as the startng module. I let the players take one item of their belongings to make the trip.
One took his car, one took his sword, another brought his laptop along, ne brought his backpack (which had his DnD gaming books), and the last player brought a paint ball gun.
