To succeed with Urdu, you will need to spend a lot of time reading, writing, speaking, and listening. These four things help to learn Urdu.
While it won’t take you a lot of time to learn the basics, to truly become proficient, get ready to devote many years to this useful pursuit.
For those who really wish to master the language, you should make the commitment to make the pursuit of Urdu a lifelong hobby. Every day, more and more people are learning Urdu, so it will be time well spent.
You will have to find good study materials, good teachers, and good practice partners. Most importantly, you will have to find the discipline to study and practice and improve regularly. If you don't study regularly, you won't make much progress, or worse, you'll make lots of progress and then forget what you've learned!
The secret to fluency (since we know you want to know) is quite simple: master reading, master writing, master speaking, master listening, improve your pronunciation, and improve your vocabulary.
Do these things regularly, and within 3 - 5 years, you can almost certainly become fluent in Urdu. The question is: will you actually do these things? Ahh, that is the question. We hope you will!
