Question

Change into indirect my mother said "be responsible and act with a sense of purpose and nothing can stop you from being a success "

Answer 1

my mother said that be responsible and act with a sense of purpose and nothing can stop me from being a success

Answer 2

In indirect speech, this sentence would be written as:

My mother advised me that if I become responsible and act with a sense of purpose, then nothing would be able to stop me from being a success.

Since the speech that the mother has given is an advice, I replaced 'said' with 'advised'. In indirect speech, inverted commas are removed and the speech is written like an ongoing sentence.
