" Important things for beginners:
" * Start out small... Don't jam your vimrc full of things you're not ready to
"   immediately use.
" * Read other people's vimrc's.
" * Use a plugin manager for christ's sake! (I highly recommend vundle)
" * Spend time configuring your editor... It's important. Its the tool you
"   spend 8 hours a day crafting your reputation.
