I wrote this for my blog and thought you guys might enjoy it :) Some of these are specific to my pet peeves, but I thought they were valuable lessons nonetheless.

Perserverance: You might have to check twelve different websites, but you WILL find that perfect freebie texture set eventually.

Self-Reliance: Renderosity doesn't carry it, neither does DAZ or Content Paradise, and Google is no help at all. Guess who's got to make it?

Acceptance: DAZ's installers are wacky and their file structures are a mess. They can't help it, it's just the way they are.

Time Management: That weekend project will turn into a full month. (But it will look darn awesome when it gets finished.)

Tradition: MAT poses and DAZ figures are the industry standard. Deal with it.

Patience: That render will finish when it finishes, and staring at the progress bar will not make it render faster.

Prioritizing: Your figure's skin might be textured down to the pores on her face, but she'll still look like a robot if you neglect to fix her dead-fish eyes.

And this wasn't exactly a life lesson, but I thought it was useful nontheless:

Poser Operator's Prayer:
God grant me the skills to make the content I can,
The cash to purchase the content I can't,
And the wisdom to know the difference.
