Language learning is a difficult task. We have to invest an enormous amount of time to get good at a foreign language, and in spite of long and arduous study, progress feels slow at times.
Research suggests one consistent theme for a successful language learner is persistence. Persistence is thought to be more important than any other characteristic such as talent, intelligence or aptitude. In other words, we have to keep going!
All of us are busy with tons of things to do and at times we feel lazy. But all you need is 15 to 30 minutes everyday to spare for your English studies. If you do so, let’s say for 6 months, I am sure you will notice great progress!
Just find an area or two (such as vocabulary building, English language for meetings, how to give presentations in English, improving your scores in TOEIC, etc.) and invest a little bit of time each day. You will certainly reach your goal some day. Good luck!
