I am 25 year old boy working in a software company in Pune.From last month i am not able to concentrate on anything.My thought are not constant.I do not have any control on myself.Once i decide to do something but not able to follow the routine.May be it is the lack of sleeping.I can not sleep more than 6 hours.Someone advised me to think positive,everything will be solved.I have checked by doctor and she also said that u dont have any physical or mental problem.Sometimes it happens that we loose our concentration.But it should be rare.How can I think positively?Give me your valuable suggestion.
