A long voyage is a series of small jaunts in succession. A large project is a collection of tasks in sequence. A long word, like sesquipedalian, is composed of word parts strung together.
Realizing this, you need not fear the Brobdingnagian events in your life…or the big words, for that matter! Take a step back, put them in perspective and then break them down into their constituent parts. Then, tackle the pieces one at a time.
When it comes to human beings, multi-tasking is never as efficient as a serial approach. Concentrate your attention and your efforts on one thing at a time and you will get much more done in a day. Resist the temptation to spin a lot of plates at once; your heart and your mind will thank you later.
