Long working hours become less bothersome when the work environment around you is healthy and inspiring. Whether you are putting in these long hours of work for yourself or for a company you are working for, as long as you are able to deliver productivity and are happy doing what you do, it does not really matter.
A coworking space is not just about the amenities and the facilities, but it is also about having an excellent work environment around you, an environment that inspires you to be productive and gives you access to networking opportunity with people who can bring in that kind of dedication and inspiration.
Find a coworking space in your city and request your company to let you work out of the coworking space. You could come across a dramatic shift in your outlook, attitude, and delivery towards your work.
