Keep a check on yourself!Start writing a dairy every-night! Even if you just did nothing but lay back at home. It would feel very annoying at first, but then after a week or so in writing, get back and read the first page you wrote... Yeah! Now you will see the difference in you and its only you who truly understand the vast change that just happened in there! If you don't feel like writing, then just record your voice at the end of the day and store it! In a week you could hear and access the change in your voice pattern and the level of confidence that just got more boosted!
