Workspace is Everything
For me, environment is everything. If my bed isn't made, I'm frazzled and frankly, a bit lazy. If the kitchen isn't clean, I don't cook. And if my workspace isn't inspiring, my work suffers.
The key to a good workspace is customization. Your workspace should reflect you, what you love, and what makes sitting at a computer screen for long periods of time more bearable. For me, it's covering the walls surrounding my desk with inspiration, things I find beautiful, and photos of friends and family (because nothing is more inspiring than the people you meet).
