Keyboard Shortcuts are your best friend

Learn keyboard shortcuts for whatever apps you use the most. Seriously... I put off doing this for years because it felt like a hassle to memorize them but once a few stick they become automatic. I can't imagine going back to clicking through menus for everything. The time savings add up fast and it just feels good about flying through tasks without your hands leaving the keyboard. Start with like 3 or 4 for the app you use most and go from there.
