Work is work.
if you take 30 minutes to do something it means
It is not challenging
You are not practicing ( studying )
You don't care about it.
If you take more then two hours it means.
It is challenging
You are practicing
Your care about it

This is any studies. It is like me studying astro physics. Do I really need to put in more then 30 minutes a day to study that. Yes if I care, and no if I don't. You can also see how much they care by the response time.
A liar will flinch and take longer to answer.
A truth person will answer quick, with joy.
A good liar will be like the person telling the truth but something is missing.
The same could be said with a person who is avoiding truth for their own personal goals. Like a suck up, taking time to give an direct answer, with or without results.
Like answering "how did you enjoy that meal". A person that enjoyed or did not enjoy a meal will be super happy about it, a person who did not enjoy the meal will use an alternative answer, no to displease you.
