Multitasking is a myth. Sure you can kind of do two things at once like chewing your food while preparing your next mouthful but one of those tasks--if not both--is going to be substandard.
To prove this next time you're eating a meal stop yourself from loading up your fork until you have completely swallowed the food you already have in your mouth, in fact, don't even touch your utensils until you've finished that mouthful. What you'll notice is there's now an extra few seconds where you can enjoy the taste and texture of your food before it slides down your throat and into your stomach.
Now I'm not saying that it's impossible to enjoy your food while pottering about on your plate with a knife and fork, no, but I am saying that the brain power you commit to slicing through that asparagus stick or chasing that final pea diverts attention away from your tastebuds and the nerve endings in your mouth, the result being that you eat quicker, you savor your meal less, and you often end up with indigestion.
The moral of my story is not to get you to enjoy your food more or to have you wind up spending more time at the dinner table instead what I want you to think about is the tasks in your life that you can either postpone or eliminate so you can do a better job of focussing. It's up to you to choose what is the most important task and it's up to you to focus on it at the expense of the secondary task--sometimes consuming food is more important than savoring. Continue to do both tasks with equal effort and you'll succeed in doing your tasks efficiently but just OK. Not great. Life is be about doing things GREAT.
A buzz term for what I'm talking about is "being present."
Generally this refers to being "in the moment" with other people like when a friend engages you in a conversation about how they just lost their job being present means that you're there making eye contact, you're listening, and at that point in time there is nothing else happening in your world, the one thing you're not doing is double-tapping on Instagram. Alas I digress what I mean to say is that being present means focussing on the most important task, and that task could be to enjoy your $100 meal.
So how does this tie back to what I'm doing and how I'm feeling? It means that since I started allocating parts of my day to just do certain tasks like responding to new backers while closing all the other tabs and programs on my computer I've found that not only am I getting each task done quicker but I'm getting it done great and the the end result is that I don't feel swamped.
