I did the between 70-90 hours every week for 18 months straight and yeah it does burn you out big time and its not healthy but I it got me the deposit to buy a house and fat deposit at that, in 20 years time when I'm mortgage free it will have all been worth it I will be able to live well just doing 30-40 hours a week. Doing all those hours the worst part was seeing how high my tax bill went.
