Without a goal, however hard you try you will never achieve anything. You need a decided, specific, written goal.
Maybe you have one already? Maybe you need a certain level of English for a promotion or pay rise? Maybe there is a special girl or boy you want to speak to in English? Maybe you have a study abroad or sightseeing trip coming up? Set that as your goal.
See yourself with that promotion, with that pay rise, with that boy or girl or talking effortlessly during that business meeting.
Set the goal, work every day towards it and you will achieve it.
