Is there a way to tell if you have too much scheduled in your calendar vs you just aren’t using your time effectively?

I have three children, two dogs, I work full time which takes 10hrs of the day including the commute, take school courses online, have activities 4 days a week and also live a healthy lifestyle with sleeping 7-8hrs a night and working out about 1hr a day. I am typically the only one putting the children to bed as my husband is preparing for work.

I am having trouble making sure my dogs get walked every night. I know I could hire someone to do, or ask my husband to however he is physically exhausted from his job so he does not like to and I do not want to hire someone because I do enjoy the walks.

I feel like I am constantly on the go from one thing to the next. These are all things I enjoy, however it doesn’t feel like I have much space to just be without having something to do.

Is there a way to tell if it’s a scheduling issue or just a mindset issue? Thanks!
