I was scrolling twitter and found this image. A reply to the post said "So long as these things draw you closer to God and make you more zealous in His service. This intention is rare indeed, and yet the manuals of theology state plainly that it is a sin to use any of the goods of God's creation without this intention." Could anyone elaborate on this? I am curious as to what intention you must have. As of now I just intend on doing God's will.

Everything should be ordered towards God. The Saints are quite extreme (that's why they are Saints) so many will say that anything that keeps you away from God is a waste of time (including (especially) hobbies).

I think that most worldly items are not necessary. For example. I currently use a old run down laptop which has many faulty keys like the ctrl key. The laptop is slow and can't play videos at 1080p 2x speed, and using keyboard shortcuts is no longer possible. Sure I would like a new laptop, but I don't NEED it. Maybe a women desires a new handbag, not needed, but in certain cases might be necessary, eg her old one is falling apart.

As per your image, the majority of people do not 'have fun' to please God but rather to please themselves. We don't have to be 'boring Catholics' and it depends on your state in life. A father may need to buy somethings for his children to grow and develop properly. I am more of a 'boring Catholic' but not currently a full 'monk mode' religious. I may go to a restaurant once in a blue moon. But I don't do the things I used to enjoy such as playing video games etc.

Say for example, parents decide to buy a new set of suits and dresses for themselves and their children, their Sunday-best having gotten shabby over the years, and the children having outgrown theirs beyond hand-me-down practicality. If in so doing, they explain that, "This is what we wear on Sundays and days of precept when our purpose is to glorify God", then they've probably demonstrated that intent and taught their children well too. Thus, it's no longer the base desire of "I want pretty clothes" as in the left side panel of that image.
