Do you carry some of your first life routines into SL? One of the things that I like to do before I log off SL for the night is to always go home. It really is nice to have a home in SL to actually go home to.
One of the habits I try to remember to do is to tidy up my inventory before I log off. This helps because all I need to do is check my recent items tab and file objects from my day. I then put on some nice relaxing music to wind down. And then I put my avatar to bed as you can see by this picture. I wonder if you have any routines in SL?
