Drift, my approach was very very similar to yours.
Instead of Moodlet Manager, I opt to go Alchemy + fast learner asap. I also use swimming in cash LTW + gem cutting maching + transfiguration table + Wish Enhancing Serum (very important !!) I also picked up 3 skill challenge on 1st day, 2 collecting and 1 consignment. With 3 skill challenge completed, I use 2 for midlife crisis, 1 for fast learner.
The first skill one of my sim level is photography. Right after I use the Wish Enhancing Serum (24 hours) I level photography. This netted me loads of happiness points -- plus 2 more skill challenge fairly quickly (photog and architectural eye). I got another fast learner + teleporter (so i can travel fast !!!!)
My other sim worked hard on Alchemy -- very important in my challenge. This is how I took care of my needs:
Hunger -- Hardly Hungry / eat a fruit
Bladder -- Steel Bladder
Hygiene -- Dirt Defiant / Mobile Motive
Social + Fun -- Vial of Bliss / Vial of Potent Bliss
Energy -- Potent Invigorating Elixir
As you can see, I didn't even bother getting moodlet manager. I found out that potent invigorating elixir actually saves me more time by locking the energy bar for 2 days. If I use moodlet, it will zap away the elixir buff (found that out when I was playing Dynasty). My alchemy toon also made lots of wish enhancing serum -- anytime i have a 5k wish come up, I will use the serum and get 10k points.
Husband Sim
Photography + Gardening + Logic + Inventing + Handiness + Martial Arts + Nectar Making + Athletic
Wife Sim
Alchemy + Fishing + Cooking + Guitar + Instruments + Charisma + Writing + Painting + Mixology + Riding + Sculpting
Horse Sim
Jumping + Racing
Logic -- I threw parties in my lot, invite teens and children -- tutor.
Guitar + Instruments -- Don't bother with star challenges. I didn't do the performing, but I had my sim play the intruments while I have party on my home lot. She finished 3 of the charisma skill challenge just by playing instruments during parties.
Cooking --- autumn salad all the way till I hit 75 dishes. Then off to the library to read cook books.
Painting -- small paintings + extra creative LTR
Charisma -- observant LTR + play during parties, then tell 100 jokes and finish off reading book in library to max.
Writing -- children book, wrote 20 books then stop. The royalties will keep rolling in every sunday, I think i got 30k by the 3rd sunday after I stopped. Don't have to write more than 20 books, just have to wait it out.
Gardening -- planted 19 kind then move on to plant grapes (for nectar challenge) and elixir mats (spotlight mushroom + wolfsbane) -- needed those for potent invigorating elixirs.
Riding -- buy lucky mount LTR on horse, then enter competition only after horse skill is max. Horse training done on home lot.
Nextar Making -- vizard of vine can be done with homegrown grapes.
Collecting -- got all the collecting. Main reason I play in sunset valley because I know all the insects / butterflies spawn point, made life easier.
Alchemy -- mix vial of bliss + potent invigorating + wish enhancing serum
Sculpting -- do 5 clays, 20 ice to get the faster sculpting unlock -- then finish off the rest of the challenge.
Inventing -- make smasher like crazy then detonate the smashers + blow up a nice expensive car.
Handiness -- I threw parties in the beginning everyday. I put out dishwashers 1st, when i got 10 bad ones, then i put out sinks. If they are dishwashers around, they won't use sink
Fishing -- fish like crazy, only fish in spots -- 6 fish per spots, move on when fish no longer jumps in the spot.
Martial Arts -- can't complete tournament. Sim Fu King is easy. My logic sim is my martial arts sim too, he teach/tutor the martial arts skill to another townie. I tutor 2 sims (prefer the unemployed ones) in martial arts skill, then keep inviting back to the house and spar.
Athletic -- didn't use moodlet manager (because of potent elixir). When fatigue, i have my sim switched to inventing, making those 100 big inventions was sooooo time consuming.
Mixology -- didn't do professor or master.
Photography -- didn't finish paparazzi, rest are pretty easy.
