Slow down your speaking speed
Your confidence will go down if you try to speak fluently from the very beginning. Give yourself some time. Start with slow speaking speed and increase your speed over time as you make more progress day by day. Slowing down speaking speed has another benefit — you will get enough time to make sentences in your mind before you speak.

Watch English movies
These movies will help you to learn proper pronunciation and improve your understanding of English.

You can regularly discuss about your improvement and weakness with your mentor. Oftentimes, she can help you. Your mentor can be someone who is good at English. She can be your school / college / university teacher, your friend or any person good at English.
Try to correct your mistakes
It is common to make mistakes. Every time you make a mistake, write it in a separate piece of paper. Make a list of mistakes. Check your mistakes from time to time and try not to make these mistakes again when you practice. These mistakes are clear and good indications of your weakness in English.
Give yourself time to think
Whenever you make a mistake, you should think how you can avoid this mistake from next time. Take time and assess your progress and weakness.
Be an advance learner
Try to learn advance English grammatical rules and vocabulary. Never be happy with your progress. The more you learn and practice, the better English skills you achieve.
Start with "Tense"
There are mainly three types of tense - past, present and future. Usually, verbs indicate the correct form of each tense. Besides learning tense, you should memorize some verbs too. Do not worry. It is interesting and easy to learn the necessary verbs.
Learn common pronoun usage
Do you know the difference between the common subject pronouns and object pronouns such as I/me, we/us, he/him, she/her, they/them?
We use subject pronouns such as I, we, he she, they when the subject is doing an action. Usually, we use subject pronouns at the beginning of a sentence. Example: I cannot remember the story.
But we do not start a sentence with object pronouns such as me, us, him, her, them. Example: Call him.
Active voice and passive voice
Many English learning students get confused here. In active voice, the subject performs an action. In passive voice, the subject and the object of a sentence swap to form the correct sentence.
Incorrect: The cinema was gone to by me.
Correct: The cinema was enjoyed by me.
A preposition defines the relationship between an object and its surroundings. Without the proper use of prepositions, your English will sound weird. Luckily, there are only a handful of prepositions and these are easy to learn.
