The outlook affects the outcome. The way you’re thinking about something affects the way you do it. A tired and fatigued brain does crap while the energetic one is more dynamic, takes less time plus makes you satisfied with the outcome.
Even though hacks are all passed on, one piece of advice is to revisit your unfinished craft with a new perspective. Leave it out when you’re exhausted and hop back in when you feel active. Decide whether you just want to get it completed or if you aspire to truly devote your time and energy towards receiving the quality upshot.
