I think we're both exagerating for fun, because well...its fun. 😀
Its true though, what youre saying in a general sense. I actually suffered a temporal burn out about a year or two ago just from requests alone from a mess of different people. But see, that was a time when I was trying to please everyone and never said no to any request. And its not that I say no now, I just don't reply to e-mails, PMs, posts, etc. I don't like having to tell people no. Thats what started the problem. Its awkward and sometimes it makes me feel bad. And I hope that by not responding they understand its not because I'm ignorning them.
Its hard to approach an otherwise friendly fan on these types of issues too. Some people even beg or plead, or insist and it really makes it emotionally trying to say no and to ask them to not reply again. I hate doing that.
I'm not some dramatic case, because I'm sure everyone has or will go through this at one point the better they get at what they do and the more people are aware of their existance.
Part of the problem for me I suppose is that its easy to find me, as long as I've posted on a site. Because more often then not I fill my profile with everything someone needs to know to contact me and I often use the same e-mail address. I get more requests for art than I do chats with random people I don't know. Its definitely not balanced.
