A fluent English speaker should have an extensive knowledge of the English vocabulary.
Set a realistic target daily and stick to it. Start with 30 words a day
The best way to remember new words is to put them into practice straightaway. Try to compose a sentence with the new word or phrase or use it in your next conversation later the same day. This way, it will move into your active vocabulary and you will feel more confident using it in your speaking or writing.
When you learn a new word, ensure that you check everything about it. Whether it has other forms and other meanings, whether it can be used in expressions and if you can build associations with it. It will help you to boost your vocabulary quickly and make learning the language easier.
