If you're not spending most of your time working on your highest priority, then it's time to reevaluate what you're doing.

My mum worked as a hotel room attendant (cleaner) everyday so that she could send me to a Catholic school and give me piano, maths and Japanese lessons, because her children, my older brother and I, were her highest priority.

Working on your highest priority could mean a number of things.  For example, a parent's highest priority could be their children, but that doesn't mean they need to spend all their time with their kids.
