Yeah, people are quick to judge a habit, but you know what works for you - so absolutely you should do it :D I've once read some pretty awesome essays (can't find them now) of about 10 artists who were explaining all the 'useless' things they do so they are / can become creative :-) It's totally fine. It's just a process we have to go through as creative people... Thanks for stopping by @artbunny!
