You might find that you need to be working in total silence. Maybe you work well if you are jamming to your favorite rock music or maybe classical music is your thing. You will learn by putting yourself in different situations, and determining how you are able to obtain the best results in your work.
Setting up your work space may be as easy as finding a nice quiet place, surrounded by trees, and just the sounds of nature to inspire you. Others may work well with lots of color and clutter around them, giving them ideas in which they can feed their creative on. This too may depend on the project your are working on. Mix it up if you need to. You work space does not always have to be in one particular spot.
Start by making notes of when you felt your most creative. If you work well from late evening into the early morning, then by all means go for it. Maybe you are a morning person and do well first thing when you get up. If you can determine what works best for you, this will maximize your creative time and allow you to do your best work.
