Sims 3 decay to fast anyone have a mod?

lionkinggaurd33  What reason is it that makes you unable to use NRaas mods?  Other mods might have similar issues.  And the mod you'd want is NRaas Relativity, unless you knew how to make your own that had the same or similar functions.

It happens on purpose so that you will aim to achieve enough happiness points for your sim to buy the happiness rewards which include:

• Steel bladder
• Zen sleep
• the hygeine one
• Carefree (fun)
• and a bunch of others that address the rest ... 

So. Play the game. Try to satisfy some of your sim's wants/wishes to gain happiness points quicker, but they do build up slowly over time on their own anyway if your sim is just generally happy and alive. If you play the load-screen game ("find the ... ") when you load your game for the day, that gains some points, which get awarded to the sim who the plumbob was last on and will be back on when you re-enter. Gifting friends gains points. You don't have to gift different friends by the way. You can gift the same friend all the time if you want, but there's a limit of four gifts all together each day or something, and the points go to who the plumbob is on. 

My sims always go for steel bladder first, that's the most annoying one especially for travelling. Then they go marathon for the big Zen sleep one, because that one costs 30 thousand. It does make a difference. 'No bills' and 'fireproof your home' are good especially for grown up children they send out into the world to live on their own. 

At university if they have enough I get them to buy their social influence so they can get the extra trait and career and all that. 

The only way I know of doing it, via relativity mod by Nraas. I'm not sure what could cause you to not be able to use it, but relativity mod is less heavy than story progression mods and such, so it shouldn't really cause issues with the game.

There are also life stages, traits, and situations where the needs decay faster ...
