Smart work is better than hard work 'is not a foreign phrase that even hundreds of times we hear in our lives. Why do we think this phrase later matters? Because now is the modern age, where life is short and we feel the time passes when we do little if we work hard, then we do only that and that is often useless. Conversely, if we work smart, we will not only save time to work optimally but also save our energy and operational costs.
