I've been doing a daily drawing for 666 days now, and I've talked to a lot of people about it.
Short answer? Absolutely, do it, you won't regret it and your art ego will be satiated more often than not.
Is it hard? Absolutely, but don't have a high bar, a little 5 min scribble is enough.
If you want to improve fast, just do it, a little bit every day, 5 mins to 5 hours, whatever you want it to be. Don't have an idea? Just pick a character you like, and a pose reference from somewhere. It does suck sometimes though, you'll be busy all day and you'll get home at 2am and realise you haven't done it. But it becomes like brushing your teeth, a little action to do regularly you barely even thing about anymore (I mean, if it's 2am, what's another 10-20 mins, we'd probably be on our phones for that time anyway let's be honest hahaha).
The worst of it is the fluctuating ego though, one day you'll draw something great and and feel good all day. But the next might not be as great and you'll feel down in the dumps... But it only last for that day, when usually it lasts days/weeks since you only feel as good as your last drawing.
So idk, just want to encourage people to draw more, make it fun, make it a habit. If your ideal job is to draw for a living, get the jump on it and begin the workflow now! You can do it!
And if anyone else here does daily drawings, I'd love to hear about it!
