Don't go from bed straight to the desk, have a well-defined separation between work time/space and a personal time/space. Don't ruin your back just because you didn't bother change your cheap, badly designed chair. Last but not least, don't let long hours get in the way of your health and exercise, otherwise you got nothing.
