Hello Massoud,

Anglophile has corrected the piece but he omitted to point out that you need to remove ‘Actually’ too.
You could use ‘actually’ to start if it were following a statement or comment which is not quite true or not fully explained. As there is nothing prior to your writing here, it is not an appropriate sentence start here.
