If you’re paid to do something, it’s easier to do than if you’re not.
I mean the actual task itself gets easier if it’s your job versus if it’s just something you’re doing, particularly for yourself.
Take something like replacing a toilet. If it’s your job, you have dedicated time to do it. You’re not emotionally stressed about it. You’re not worried about it before or after. And you aren’t scrambling to find the time to do it – or dealing with the fallout of other missed responsibilities because this took priority. Those factors, the stress, the worry; they make any job more difficult, even if you have the same training.
It’s good to simulate that in your own life if you can. Build room to deal with emergencies as a professional would, not as a stressed individual. It’s not always possible, but the real lesson is keeping your life from being too overfull.
