Favourite skill?

Wellness skill is my favourite. As well as boosting fun, yoga boosts inspiration and focused moodlets which boosts other skills and usually lasts about 8 hours. Also meditation can quickly get rid of negative emotions like stressed and embarassed.

Gardening is always my default when I start a legacy. Gardens look beautiful, especially with seasons. With Eco lifestyle you can make fizzy drinks with what you harvest.
Other skills I love, but not as much as gardening are wellness, music and charisma.

The cooking/gourmet/baking skill is my favourite. The painting skill is a close second :)

Rocket science

in terms of practicality I'd say handiness but in terms of fun I couldn't choose, I really like the creative skills so any music skill, painting, writing, knitting, fabricating, juice fizzing, robotics....also yoga is cool to watch...I really couldn't choose.

Robotics. Rocket Science is a close second and was my favourite until DU came out.

My favourites are the creative skills : painting, writing and woodworking. I like my sims to actually create things.

I usually pick my skills based on the Sims and their stories, but they all have some merit and fun. I usually like having high cooking skills so I can make a variety of dishes, but many skills do not have something intricate that I use very often.

I am liking the recent trend of having a special trait reward for high skill levels, though.

Handiness, it's useful for a lot of things. Fixing broken appliances, upgrading appliances, the seasons machine, the hidden lot in Oasis Springs, etc.

Robotics, Fabrication and Archeology have to be my top three, so much to explore with these three skills.
