Just check for grammars and structure of sentences

1. Does / Do anyone know what it takes to be a successful person?

2. Does it really help to set the goals? or Do it really helps to set the goals?

Just check for grammars and structure of sentences

1. Does / Do anyone (anybody) know what it takes to be a successful person? OK.

2. Does it really help to set the goals? or Do it really helps to set the goals? The correct one.

3. Do such things matter while making decisions? OK, but I would prefer to change it : Does it matter while making decisions? Are the things so important to make decisions?

Best wishes.
