Overworking and being ready for new tasks 24/7 might be a good start for a newbie, but it will shape you into a burnt-out pessimist in the long run.
The major skill of a designer is to rethink things, and there is no way you can reimagine and rethink anything while depressed. So the key lesson I learned for myself is that it is crucial to thoughtfully add new impressions, events, and people to my weekly routine.
This way, I get energized and inspired by new things. It is the shortest and the most natural way to direct one’s knowledge, creativity, and motivation into a productive workflow. Leave some free space for thinking it all over in silence though!
