Why does adderall make me focus on everything except what I have to focus on?

God damn, it's so annoying. I'm prescribed 20mg tablets I'm allowed to take up to three times a day instructed by the script. When I take it I sure can focus better, but it's always on shit like talking to people on the internet, doing crafts, or playing with my cats. I can never focus on things like work or the cleaning I desperately need to do in my apartment. Does anyone else struggle with using the attention adderall gives them to do the stuff that needs to get done instead of the fun stuff? Any advice?

Thank you
