Unless you’re working 16h per day, every day, you have time to cook.if you are single, sure. but as soon as you have family, those calculations go out the window. worse if you are a single parent. long commutes, a stressful job...
8 hours work, 8 hours sleep, 1 hour commute, 1 hour lunch, 1 hour in the morning, 1 hour spending time with my kids (means i do what they want), 1 hour TV to relax. 1 hour exercise/go for a walk. that leaves me with 2 hours for everything else. housework? shopping? keeping in touch with others? go out to meet friends/family?
i love cooking. i did it all the time before i got married. i rarely went out to dinner. but as soon as i got married i had to stop. i couldn't afford the time that i needed to dedicate to it to do it right. it's more than just the process, it's the planning, the shopping, etc.
it's not a question of time, but priorities. for most people 18 hours (sleep, work, commute, lunch) are spoken for, and everything else has to fit into the remaining 6 hours. yes, you can move things around. you have time to cook if you can delegate. that just never worked for me. at best i can delegate washing dishes and other housework.
