What sort of schedule do you run? 8 hour days - 10 hour business days - 12 hour mixed days - 7 day weeks or 5 day weekends? Almost everyone differs but with an intention to make it big in business and entrepreneurship its a common case to work 7 day weeks. Personally I find about 70 hour weeks work best and I am a firm believer in early rising. Getting up at 5 am makes you feel like you have got a ton done before people are even driving to work.
My typical day runs from 5/6am to 5pm (12 hours working - usually stopping occasionally but not really for lunch), followed by a few hours of relaxation and dinner - followed by exercise and a bit of blogging/business in the evening.
And the general concensus when you read websites like forbes or books written by millionaire business men (by the way I don’t suggest it - if you do pick well - business men are business men - chances are someone else wrote it) is long hours definately help - most suggest starting between 4am and 6 and some finish at 12pm or even later.
The trick as ever IMO is objectivity. Long hours are great if they are leading to an eventual profit, goal or anywhere positive. But too many hours can exhaust you and lead your business to fizzle as you don’t instantly see progress for your ‘Insane’ hours, so if working more than 12 hours makes you need to have a week off every month don’t work 12 hours a day! If you think of your business as your corporate personality - the more stable you remain the more stable your business will be!
