Today I read an article regarding the English skills of famous stars and how they learn English.
Some guy said that if he had as much money as those famous stars, he would also get the English skills. I think this is wrong, what the good English skills need most is practice, money is not the most important factor. You can see that those famous stars also need a lot of practice, even though they have hired English coaches to teach them.
You can spend your time doing the work to replace what the money can do, for example, go on the internet to find free courses, materials or even different methods, and practice according to the methods. There is tons of free materials that will meet your needs.
