I have read posts of these kind for quite some time. All of them suggest. ... Wake up early, exercise, work for 2 Hrs and then get ready for normal life. I have been trying to do this but failing miserably, cos my body doesn't cope up. I say start exercising regularly once it becomes a routine then start working on your start-up.but don't forget exercising. Having said all that it boils down to one point. WILL POWER.
