Yes, it is very normal in an unstructured life, many very smart graduate students at the top universities struggle with it. It is the curse of freedom. People don't realize a regular 9-5 job gives them routine, social commitments and a visible positive feedback on a good job done in a timely manner, and a negative feedback otherwise (both positive and negative social feedback are stronger than self-awarded rewards and punishments).
