I will only work a 9-5 schedule (8-5)?

Ha yeah the topic says it all
I feel like im wrong as an employer just to say I will only strictly work 40 hours a week but thats just me But I will work hard and be very productive those hours I sure will not live to work and weekends will always be mine in bed sleeping.
What do you guys think? theres more to life than just work right:)?
Im good enough earning 40k to 60k
I sure dont need more than 60k
