I think it's too easy to blame. We wouldn't look at a watch that was running slow and say "that watch is lazy", and we shouldn't look at ourselves when we don't achieve what we want and treat it as some kind of failure of will. Psychologists have a term for when you overestimate the actions of a person rather than the environment they're in: the fundamental attribution error. We attribute results to the ego even when it's not really responsible. Your mind and body are incredible machinery that you spend most of your life figuring out how to operate. The difference between 20 and 30 is ten years of operating experience. If you've blown it this weekend, it's not because you were lazy, it's because your machinery's not quite running right. The advice given elsewhere in this thread is great, but at the core is an understanding: the results mostly come from your environment. Not just the external (distractions, workspace, tools etc), but also the one in your head, defined by goals and motivations and ruled by systems and working rituals. You can't change it all at once, and if you expect that the next time you sit down on the weekend you'll just have a new lease on life, you'll be disappointed. If you do this right, you'll just slowly start finding it easier. The distractions less appealing, the tasks more approachable. Eventually it will be harder to fail than to succeed. To get there, you just need to stop blaming the watch, and start listening to the machinery. What does it need to run on time? PS. About founders working hundred-hour weeks without breaking a sweat, I think you'll find the number changes significantly depending on how you define work. I'm currently working 168 hours including scheduled rest breaks and group-oriented social activities.
