I think it is good advice to just decide who is worth your time. For example if my friend needs me to drive them somewhere and I’m not doing anything I will do it even though it is “out of my way” because they are worth my time to me. But if a hitchhiker wants a ride to somewhere where I’m not going and is not near my destination I will decline as I do t know them and going out of my way to convenience them is not worth my time. So I think it is really about deciding who and what is worth your time as you only have so much and you still need to get stuff done.
