It's basicly a hard thing, becouse you need Painting, Culinary, Sculpting, Gardening and fishing when the first immortal is tipping to the other half of the elder stage... Training spouses isn't as easy as it seems. Rather have the 1st 2 max several skills and then have some careers like Inventing, music, acting etc...
1 question - Do different branches count as 2 different maxed jobs or not? (Actor and director for example)
