This morning I thought that if we brushed our teeth with two toothbrushes at once instead of one we would save half of the time we spend on this process. What other ways to save time do you know?
Listen to the radio while reading your message lol! Just kidding^^
I guess the best way to save more your time is :
To do the right thing at the right time in the right place.
As for your method to save time, even that is true in some case, but you have to know most of the people waste much more of their time on futile things that makes them feel so tight in time.
You could try combing your hair with two combs, one in each hand [like the toothbrushes, I presume], and shave with two razors likewise. It helps if you're ambidextrous; otherwise, it might just not be worth the effort !
I dont think it is a good idea to brush teeth with two toothbrushed, that's weird.
Time flies, what we need to do is enjoy life.
