To be productive in a new job, what can you safely ignore

Well, these are the ways u can be productive at a new workplace:
-do the difficult or most important stuff first, then leave the less complicated stuff in the end
-take breaks-sitting 24/7 in ur office desk can be detrimental to ur health-do things u enjoy every one hour or so, such as sipping a black coffee with a light snack or having a quick laugh with ur colleauges, or perhaps u can challenge urself with a game of scrabble. it will change ur life of work struggles and make u mentally and physically happy!! 
-don't multitask-u will make ur life more complicated, by completing stuff in a second. don't be paranoid with wotever work u have, the world is not going to end!
-u have innovative thoughts but finding it problematic to execute it? write down some ideas, concepts of how to overcome some work problems or doodle of wot u see ur next digital future like. its not complicated, u just need to be experiment, u never know when a creative idea might rush in.

-i hope i helped:)
