Feeling Frustrated with My Art

I've been so frustrated recently abiut my art. On social media I see so many people rising to the top creating wonderful finished works, detailed and furbished. Meanwhile I have so much trouble even starting and staying motivated for a piece. I usually just sketch it out and abandon it. I've tried coming back to them the next day but by then the inspiration is gone. Sometimes I can't even assemble the shapes to make coherent lines. I've tried many mediums. Digital art is my top. Traditional, painting, finger painting frustration. It all ends up a faliure some way or another. I miss when I was younger and had more pip to my step. I could finish works, granted not all, but at least something. And for some reason it's died down. Sometimes I even blame graduating high school because every time I was bored sitting in a classroom, I could always pick up a pen and think of something. Now I rely on my own wits. I'm just really frustrated and afraid this means I can never pursue my dreams as an artist because of it. Wanted to be an animator a long time ago, but I didn't seem to have the patience for it. The inspiration would die the next day, leaving the day's previous work unfinished.
