How do you get up and do things?

I’ve just restarted vyvanse (I took it for a month then was off for three weeks due to supply issues and then insurance issues). I know it’s not going to give me motivation; I know action begets motivation. But how do you get started? It’s like my butt is superglued to my chair! I have two to three tasks to do each day, two on the days I work, three on the days I’m off. Except Saturdays, those are specifically for hanging out with my kiddo. So I have my tasks delegated, I use goblin tool to break things down for me, I just don’t know what else to do to get started!
