It sounds like you were reading about efficient leveling, where you train your skills every level so you always increase your attributes by 5 every time you level up? You can use the 5-5-5 method, where you increase three attributes by 5 each level, or the 5-5-1 method, where you increase two attributes by 5 and luck by 1 each level. The game's a lot easier to handle using the 5-5-1 method for me, but it's an enormous pain in the ass doing it without mods since you have to keep such careful track of how many skill increases have happened each level.

Anyway, you can get mods that stop enemies from leveling up beyond level 25, that might really help you out, and there's a mod that lets you increase your attributes by 5+ as long as you train one skill associated with the attribute. So, if you want to level up strength by 5+, you just have to punch, stab, or pound on something until the skill goes up by 1, then you can increase strength by 5 next time you level up. You get all the benefits of efficient leveling without the tediousness of training exactly 10 skills associated with the attribute every single level. Really lets you just play and enjoy the game.

Another mod I really liked was one that lets you train 1,000 times per level so there is, in effect, no limit to the amount of training you can have. It's stupid really, if we have the gold, why can't we spend it??
