It took me a while to start enjoying Twitter, let alone utilizing it in a way that is more beneficial to my business. Like... I really love interacting with my fellow models. But I am teeeerrible at remembering to tweet promotional posts - wishlists, my store links, gifs, etc. Stuff that can actually remind people that I've got plenty of stuff for them to buy!
So what I'll do is sit down every few weeks, and write up all of my promotional tweets, and I use Tweetdeck to queue them up for posting (though I don't really recommend using it for GIFS because it still goes by the old Twitter gif size limit - pictures seem to be alright though!). This way, the more repetitive (for me) promotional posts just post themselves automatically, and I don't have to worry about remembering them anymore. That takes off the pressure of being business minded, and I can spend the rest of my week posting favorite video links and fun, more personal tweets and interacting with my fellow models. It's also handy if I have to go out of town or something - I can make sure I don't have tons of radio silence, and can still promote myself while going out into the real world and having adventures.
There are a few different programs like Tweetdeck - Hootsuite is another similar website I've heard mentioned, but I've never tried that!
