The second difficult aspect of learning a new language is that learning a foreign language necessitates active using of it.
.... exactly.... practice is the key to improve fluency.
For example, a learner of English language cannot prove his skills in English unlessif he travels to a company where people speak English which is not always accessible by the learners.
.... I don't get your idea in the second part.... why you specify travelling to a company where people speak English? Sounds confusing to me :(
In conclusion, learning a new language is an interesting and profitable thing beneficial , but it is also quite difficult because it demands hard efforts... Finally I would like to ask how much the French quote "vouloir c'est pouvoir", which means if anyone is eager to do something he can certainly do it, can be applicable in learning a new language
I think you better stop with the previous sentence.
In conclusion, learning a new language is very rewarding. However, it is a tough challenge because it demands lots of hard work and practice.You have a great essay here with real good points. It's just what I mentioned above that doesn't agree with me.
Good job friend!
