Starting problem is the big problem
I have seen many Spoken English beginners trying to learn everything before they speak a single sentence. Because they fear of making mistakes while speaking to others. It's not at all an wise decision to not to speak even a word unless you learn every aspects of English grammar or all the conventional ways to speak it. Try to get started with what you already know. Surely you will be making mistakes.And you have to learn from your mistakes. It's better to start speaking with yourself and your near & dear ones who wouldn't mind your mistakes & rather point out your mistakes so as to enable you to correct it.
You need an Open Mind
You must be having an open mind to take the inputs. I have dealt with lot of English speaking aspirants who are having a lot of ego problems. A great barrier to success indeed.
Take it Easy
Do not emphasise on grammar first. Yes you need to know grammar in order to speak correct English. But I request you to just take a moment to think how you learned your mother tongue. You got lot of inputs from the seniors and the fluency came spontaneously and naturally. Here you can apply the same principle to speak english. To make it happen you need to collect positive inputs as much as possible from around. Inputs of how good English speakers speak. You have TV with you. Better watch movies with subtitles. Listen to friends very carefully while they speak and try applying those when situation comes. Listen to English songs. It may so happen you won't be able to understand the lyrics. Internet is there to help you find that. Read English novels of your choice and good conversations.Consult dictionary only when you are coming across unknown words.
Get Started
So the message I want to deliver here, Start Speaking, Learn from mistakes, Write in English,Think in English and dream in English if you can (ha ha). Get started. Success ahead.
