If someone says, let's go on a roadtrip this weekend, in your twenties you'd say "Yeehaaa! I'm in!" without a moments thought. If something else was planned, you'd either excuse yourself or just not show up. What does it matter anyway, you're only 22!
In your thirties, with a child, mortgage, consumer debt, bills, and a job, you're constantly checking your schedule because there might just be a birthday party you're suppose to attend with your daughter, or there's a lack of funds flowing in at that particular moment because you just had to repair your furnance. Whatever it is, your response is not "Yeehaa!", it's more like "Oh. I don't know. Let me get back to you."
I wish I could yell Yehaa! some days, but most of the days, I'm happy to say "Let me get back to you". I don't mind plans made in advance, because I can savour the moment when I'm going to go see the girls with a bottle of wine and some tapas, or that weekend retreat without my darling girl seems rather intruiging, but I don't have the luxury of being spontaneous to the fullest and frankly, I'm ok with that.
I don't waste my time often. I do head to bed earlier than I used to because between work, commuting and making sure my girl is alright and tucked in, I'm tuckered out by 9pm. I'm ok with that as well. Chances are I'm in bed reading, not really sleeping. It's my time. Ida time.
I'm also less spontaneous because I prefer my home to any other place in the world. Sure, a weekend in a hotel somewhere luxurious is positively amazing, but home is where my heart is. It's where I am at peace.
So, time is a luxury and I urge everyone to slow down and not wish time away. Ever.
