I have not been able to maintain a proper sleep schedule since forever now it is hindering my ability to be more productive as I'm mostly sleeping during odd day times, I feel the major reason for this is my mobile phone usage as I use my mobile around over 9 hours each day, when I lock my mobile, my sleep pattern improves itself for a few days and then I start watching lot of TV and it spoils again or I start reading books or writing something, always night time. I cant understand is it due to lack of self control or discipline, I want to get my sleep pattern right...
