Just saying what cannot be changed if you want to do something that you intend to do, you do not need to say much just started doing it better come talk every day, but nothing changed.
Mere words can not change anything if you want to do something that you intend to do, you do not need to say much, just do it better than you started talking every day, but nothing changed.
Only words can't change anything, if you want to do something that you intend to do it is not necessary to say you just start doing is better than saying every day but nothing has changed.
