Do one thing at a time...for a stress free day.

Do it mindfully. Do it well. Enjoy the satisfaction. Then go on to the next thing. Multitasking might work for computers, but humans have yet to get the hang of it. It leads to careless mistakes, shoddy work and unreliable performance. Worst of all, having to do things over. This is no way to live. Give what you're doing your undivided attention. Take the time to get it right. And enjoy the experience.
