Any advice or tips and trick for an inspiring concept/illustration artist in planning his/her day out. What I mean is how much time do you need to invest in the creation of different parts of a portfolio, doing studies.. etc. I'm awful at planning those and I'm also kind of stuck, not knowing where to begin or how. PS. Especially if you're working 9-5 ':D Thanks in advance, and hopefully my questions are understandable as English isn't my mother tongue.
