'I understand English very well, but|am unable to speak English' - My practical tips for you

"T understand English but I am unable to speak it". This
problem is so common, millions of people face it.
There's a frustrating gap that one feels (between
being able understand English vs not being able to
speak English).
But don't think that it's a problem. I want you to
change your attitude towards it. Just think like on the
scale from 0 to 10, you're currently somewhere on
3-4-5. So you just have to increase your standing on
that scale.
Think about other languages you don't even
understand. Do you understand Russian? German?.
That means you have a great headstart with English.
Most of the work has been done already.
Understanding a language is no small feat. And it's
the second language we are learning after our mother
tongue after all.
Speaking is a separate activity for which you have to
train yourself separately. Since you already
understand English it will not be too difficult.
What's missing are 2 things:
1. Proactive practice
Don't wait for situations and depend on them for your
practice. Proactively make time and effort and
practise English. To start with, try practising daily for
15 minutes.
2. Courage
In addition to practising, you have to show courage
when situations come which require you to speak in
English. Don't run away. Don't be afraid of making
mistakes. Show some courage. You'll soon realise you
were making a bigger deal out of it than it really is.
