Lifestyle

Our lifestyle has changed enormously in these days if we compare it with the life that our ancestors were used to have.
Today we live in a demanding society, which makes our life lives run out of time faster. Obviously, it is due to the time we spend in working and required to go to work. (It would sound better if you avoided repetition, e.g.: "...due to the fact we are required to go to work and spend so much time there.") As a consequence, people tend to have less fewer children and to live in a stressing stressful way. We are always thinking about the way to save any time to enjoy a little the life a little.
If we spot in the look at the way we do our cooking way, there is a huge difference between what our grandparents did and what we do. Although some decades ago women spent a lot of her their time cooking home-made meals, today we today spend just a few minutes to prepare our elaborated meals, since we do not have enough time enough to do it properly in an appropriate way.
According to tRegarding the education of our children, people should follow the steps of their grandparents. Parents should take part in education and share most of the time playing and speaking to them, and quitting extra classes in order to have them less occupied with unimportant things. This is to say that parents should bring up their children.
To sum up, I believe that, on the whole, our lifestyle has to be adapted to the society but there are lots of tips advices make given by experienced people to take into account to reach a goal in our lives.

A few notes:

It is common to hear people say "less children", "less people", etc. However, since children/people/etc are countable plural nouns, the correct way is to use "fewer" when indicating a smaller number. (compare: fewer mistakes - Cpl /vs./ less water - U )

"Enough" is used before a noun, but after a verb. Example: "We have enough money" vs. "I've had enough!" or "That's enough!"
