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.

I love the painting, but like others, I also love the Eco skills, handiness, flower arranging, writing, all the skills for creating.
