What time of day do you start your work art?
I don't really do it for a living, so it's just whenever I have free time! Usually in the afternoon or evening.
What do you do when you feel sleepy and unwilling to continue working?
If it's still early I try to psyche myself up by watching art videos or something else inspiring. Otherwise I'll take a break and do something else!
Does your back hurt you from sitting on your chair?
Only when it's for long period of time! If you're going to be sitting in your chair all day try to cushion yourself. Taking breaks from time to time and sitting up straight help too!
What do you do when you feel cold while working while clothes do not help you feel warm?
Drink some nice tea and pile on the blankets! And if you're a little older there's something else you can drink. ^ _ ^
Do you continue your business constantly every day or do you stop for a few days at a time?
I try to work on it every day, but skipping a few days at a time isn't a bad thing!
Do you have tips or experiences you want to tell people about? Come here, please.
I'm not too experienced, but I'll just go with "Don't be afraid to fail!"
Making anything, even if it isn't what you envisioned is way better than not doing anything! Also, try not to strive for mental images too much. I find that when I try to hard to recreate something exactly as I see it in my head, I get way too discouraged. It's much more constructive to work from what you have and improve from there!
