Know your tools. Take some time to explore them. Knowing shortcuts, the capabilities of your IDE (and plug-ins), libraries and many more will look you like a wizard to others and can save you many efforts.

In two months using PHPStorm, the autocompletion saved me 50 000 characters. Two months. 50 000 characters.
I can't understand people who dislike autocompletion (and this is the main reason I don't use only vim, autocompletion is nowhere near Jetbrains level)
