well obviously this is a YMMV situation, but here is how i feel;
1. cooking is a pleasure, not a chore. The time i dedicate to cooking is ME time, it relaxes me, because i have control over the situation, and i get to exparience the pleasure that comes from doing a good job.
2. if you have time constraints, there are recipes - many - which will suit you; throw a bunch of stuff in the oven and watch it magically become a dinner.
You don't need to *every day* cook something labour-intensive in order to make good food, and if you have a family, you can easily learn to make 8 portions per cooking session; and which dishes keep better than others.
Being "a good cook" is about, mostly, two things: understanding the various processes of food prep - how do they work physically, and what impact do they have on the food - and being able to eyeball taste. That way you know you can turn X food into Y meal by doing Z cooking, even if you've never done it before, and can expect to make it come out reasonably good.
To toot my own horn, i can watch a cooking show on tv and know what the food taste like, by seeing it being cooked. My head can visualize the flavours, becausecooking is something that, as a euro, is always on my mind.
I like to, say, be at work and think "today i want to try cooking a meal using X that's being prepared the Z way" and then rush to the supermarket to buy the ingredients, and then home to cook, and i like to do this, it's one of the things that makes my life enjoyable. If you're not like that - more so, if you can live without doing this and it doesn't bother you at all - more power to you, but, you should really learn at least a few good recipes for those around you, because cooking good food is a very much valued skill in common society.
