I used the computer to chat. The "chat" interaction does not add anyone to your relationship panel. "Trolling teh forums" is also good for raising Social, but you do need to buy the first Mischief skill book. The best I've found is the microphone. "Telling jokes" raises Social and Fun.

I did make a few tweaks. His living space is 8x8, but he can go out of the living area (not outside the lot, though) to do certain activities, such as the rocket, observatory, and microscope. I also moved his garden out of the area once he maxed gardening and Freelance Botanist. A gardener does come in to water, weed, and spray the plants. My sim does not talk to him or otherwise interact with him. I also used a mod to permit him to collect items (It places rock formations and fallen logs in the debug menu which then can be placed on the lot. In addition, I used debug and moveobjects to place a corner of a fishing hole in his compound.)
He has completed 5 Aspirations, a total of 36 Aspiration levels, and maxed 10 skills. He is on week 20. No critical needs and no utilities shut off. In addition he has complete 2 collections (Postcards and Space Prints).

Right now all he needs is $130,000 in order to build the final additions to his house.
