How much time do we spend in urban transport on the way to work or school? If you have your own means of transport, this is zero units, but in the latter case it is often a lot of time that can be spent.
And if so....
I thought so much that it was worth to use the time spent in buses and trams. Clearly, you won't pull out your laptop and start doing your stuff, but you can remove a book or e-book reader without any problems, and the author of your favourite blog will be happy if you look at it!
Let's say you travel five times a week by bus, let's say that the time needed to reach your destination is 15 minutes. Then you have to go back, another 15 minutes. When we count it, you spend 150 minutes on your journey alone, within a week. Note that this quarter of a hour is often much longer due to urban traffic jams, but already 150 minutes, which gives us 2.5 hours, is already impressive. It is definitely better to spend time reading your favourite position than watching a busy city. Within a month it will give you about 10 hours, which you will spend sensibly. Think about it!
A penny to a penny and it will be a room. Here the penny is time. If you make sure that every minute is used sensibly, these minutes will soon become a large package of knowledge.
