“Understand that the Internet is not life nor does it make a good Second Life. It’s a part of life, but it needs to be in its place.
If you spend a lot of time on the Internet, remember this fact that is already in your subconscious: your life is limited. If your surfing habit does not change, imagine how you would feel looking back on life and seeing all the wasted time in things that mean nothing. The same holds true for video games, especially MMORPGs. Remember, all the loot you get, all the levels you attain, all the quests you complete and kobolds you slay, mean nothing when you log off. However, there is one thing that will change: you will be older than when you started.
