Don't just try, "do" instead.
If something doesn't work, keep moving on, look at stuff that inspires you, try new things, give yourself some project, work under restrictions, pixel things you enjoy, start pixelling for a game or something. There are countless options out there.
Or even better, try to find why you can't be bothered to. Too much work? Or perhaps you've become tired of it?
If anything then go with something else, after all pixel art isnt the only way.
But really, no one is going to feed you for just having your mouth open. So either find something that works for you, or starve.
