I sleep like 3 AM to 8 AM. Rest all time into studies with 15 minutes of photography , 15 minutes of evening walk and an hour of social media / debate !!
I get around 16 hours for study , 12 hours daily is must . Rest 4 hours vary completely. In those 4 hours , I may take power Naps , read novels , play guitar , or just surf through random financial news and happenings around world coz I love Economics ..
