1. Play Moderately. for someone who have been playing video games since elementary (blame it on my bros). second life can be addicting. some attraction of sl is you can be anyone you wish to be, you can shop, talk, date, play while doing it anonymously without leaving home. it's unhealthy playing too much, don't make this your world. you need to get out there, have a social life! it's all about balance. never neglect your First Life.
2. Skins Varies depending on Shape. when I was new. I didn't know the difference between skin and shape. I thought shape is for the body and skin is for the face. I didn't know the shape affects the facial features. I used to be frustrated every time I like a skin and I don't look exactly like the vendor ad. I thought skins gives a fix facial look like the ones on the vendor but it doesn't. if I want the same look I need to get the same shape that was used with the skin
3.If you can't find it, it's in the Object Folder. I remember purchasing an item and can't locate it, after minutes which seems like hours I found it in my Object folder then surprised that I got a box instead! those are the days haha and I'm like what the...I didn't purchase a box! some items are packed in a box and you have to unpack it that's why there are free to use public sandboxes to unpack things.
4. Set/Fix your Windlights to Neutral. don't depend on region windlights that changes depending on SL inworld time. you don't want to shop with a midnight enviromental setting do you? esp if you are demoing a skin. that time I just got a new skin and I can't figure out why I look so ugly sometimes, I didn't know it's my windlights. then one time I went shopping it was evening in-world. I have to wait till there's a sunlight coming through the place so I can take a better look at the item. yeah, I was a newb. .a cute newb. Check Strawberry Windlight Settings HERE
5. Don't be scared if you see avatars with massive boobs and beyond normal ass walking around. don't question their fashion taste, don't ask them why their boobs are so big or why their hips are so wide apart. don't even think of asking them..just don't. *wink.
I hope you find this helpful even though English is not my strong suit.
