By far the biggest thing I've learned when it comes to my own productivity: find a way to block out social media and other distracting websites for set periods of time. There are quite a few good blocking apps out there if you do some searching. My personal favorite is Focus (Mac app) - https://heyfocus.com I have zero affiliation with them, I just use it and it works perfectly. Good way to set aside time to crank out work, then take a five minute break to recharge when the timer is done.
