I can't begin to imagine how you are coping with such situations.
I mean checking out each picture and finding the best from them is not something easy. Especially, you hold such contests everyday. More of all, now there are more photography sectors.
I think you should start planning right away how you are going to manage it.
I don't think you spend all your time on steemit. Neither you should.
Take it easy and keep up your work. But don't overwork yourself.
I am saying all this because I enjoy your contests. I hope I am not irritating you as you know yourself more than me.
Anyway, Thanks for all your hardwork. :)
