I need quick helpful tips to get me to concentrate

This is your problem. You think there is a "quick helpful tip to get you to conentrate".

There isn't.

If you're truly incapable of doing something you're supposed to in the face of all theoretical ability to do it (time and available resources), something might be wrong. Maybe you're just too bored with what you're supposed to be doing - which means you should be doing something else. Maybe you're too tired. Or depressed. Or lonely.

Maybe nothing's wrong and you're just lazy.

If you really thing something's wrong here, talk to a doctor about it. They can help you treat the root cause.

But there's no magic way to suddenly want to do something you don't want to do. You either do it and tolerate that you dislike it, or you don't.
