I have a hard time getting focused. Takes about 5-10 minutes after I sit down to get into a groove of whatever I'm doing. Then after about 10 minutes of intense focus/productivity my wife texts me "Hey, can you come help me for a second?"

so 5-10 minutes later I'm done helping her and then takes me an additional 5-10 minutes to get back in the groove. Then after 20 minutes she asks me to come down or she comes and asks me another question which resets my focus clock.

So, 30 minutes go by and in her head she thinks "wow, you had 30 minutes of productivity, did you get a lot done?"

no, because I was only really focused for about 10 minutes without being interrupted.

I imagine this is not unique to me, but to many with a wife/kids at home.
