Give me 15 minutes of your day

People tell me they have no time. No time to study English. No time to study Spanish, or French, or German.
Folks do not have enough with 24 hours a day... and they are right. 24 hours is nothing... But how about switching to a new angle? How about talking about minutes instead of hours? One day has 1440 minutes... that is time, isn't it?
And how about if I ask you to invest 15 minutes out of the 1440 every day? You still have 1425 left to do all you want. Not a bad deal at all.
There is a catch to this deal, of course. I ask you to invest 15 minutes a day of your attention to learn a language... but every day, without missing one day, Sundays, festivities, holidays, vacation included...
How about it? Deal?
I can promise you that you will learn and improve (English, Spanish, Yoga, reading, typing...) a lot if you invest 15 minutes a day, every day, every day... EVERY day!
