Assuming Mac: Alfred for OS such as searching and opening apps, using spaces to setup smart project areas, divvy app to quickly size and move around the windows, terminal shortcuts to open files in the OS or in an editor, transmit for hidden files and dragging between panes and server + occasional mounting for preprocessing, inbox-zero mentality, a properly setup google drive app so you don't email forked files back and fourth, beanstalk for deployment of larger stacks, surge.sh for targeted front-end sites, Ember CLI or brunch for build pipelines, CodePen for UI experiments outside of the project, slack instead of email, pick up the telephone and just call for clarification more often, stylus is easier to maintain then scss, hire designers that actually know what their job is if you can. For arduous WordPress administration, rightclick open in new tab for everything - or half your time will be pushing the back button, wp-migrate pro, and in general try to get out of WP when you can.
