Spend 15-30 minutes on your artwork then take a 10-20 minutes break. During break time, move around, have a hot drink, do something completely different from art. Then resume your work. Have a time or stopwatch near to monitor how long you been working. I use my iPhone to time myself when I am drawing or writing. It helps me not to overwork and reminds me to takes breaks. You will be surprised 30 minutes on working gives you enough time.
Plan your week: create a weekly planner chart. I typically do artwork and writing three times a week. This keeps me organised and manage my day. Sometimes I change my schedule. Keep it flexible.
Try to do creative work in the morning. The brain is more active and fresh. Better natural light coming in to see the colour hues clearly. If you have not much natural light coming in, a Daylight lamp will provide extra light.
Make creative work your top priority before doing other task.
If you can not work at the morning, maybe 1-2 hours before bedtime. Some artist found doing creative activities before bedtime, it can be very therapeutic. Schedule in the day that you have enough time to focus on your creative work.
Don’t not put the TV/Computer on (unless you are working digitally). There no need to put the computer on if you are just drawing or painting. The computer/ laptop can be very distraction.
Mute notifications on you phones or small devices . You want to be able to forces on your artwork without distraction. my notifications are switched off. I like have no concerns or distraction.
Listen to music that motivates you creativity. it can be any music. relaxing, Ambience, nature or Lo Fi Music good music for Focus.
Only do one task at a time, try not to multitask. it not good for productivity. For example draft on day then outline the next day, then the next colouring. Keep it small and manageable. Avoid trying to complete the artwork in one day. It good to leave the work and come back to it a couple days. it good to get a fresh perspective from resuming it after a couple of days, to see what you noticed and what could be adjusted.
Do 5 minutes sketch doodle to warm up first. At first the brain may be reluctant to work on anything. Do scribble, draw small thumbnails, make marks. This will ease you in to drawing. Make the sketches very rough and bad.
