<i>it just seems time is too valuable (after working 9 hours a day and feeling pretty tired) to work on some stupid idea just for fun when you know it will lead to nothing</i><p>I&#x27;ve had that before, with an idea that&#x27;s fun, but not fun enough. I thought maybe I was getting sick of programming.<p>Now I work 9 hours a day, feeling pretty tired, and still go on to work on my idea until 1am or 2am. 3am if I can make it.<p><i>If you aren&#x27;t energetic enough to work on an idea for fun after 9 hours of tiring work, the idea isn&#x27;t fun enough, and not worth quitting full time employment</i>.<p>But on the other hand if despite 9 hour of tiring work, you find yourself working till the wee hours every night working on your idea, perhaps consider maybe there&#x27;s something interesting in your mind?<p>That&#x27;s the situation I&#x27;m in. I&#x27;m planning a year or two without working in a year&#x27;s time to work on this idea. Not because I have no energy to work on it after 9 hours of work everyday, but because the idea is so interesting to me even after 9 hours of work, I find myself working an additional 6 hours on it. It&#x27;s on my mind in the shower, on the way to work, at lunch, in afternoon tea break, on the way home, eating dinner, when I am working on it, when I&#x27;m in bed, as soon as I wake up. (And I try to resist thinking about it when <i>the</i> director of the company is sitting next to me. I hope he didn&#x27;t catch me writing this comment. ;)) My ideas were the same ones I&#x27;ve had for the past decade, except I&#x27;ve refined them as time gone by. An idea that was once stupid and won&#x27;t lead to anywhere, is now an idea I can&#x27;t take my mind off, an idea, for me, that will lead to <i>everything</i>.<p>Keep living. Look for a new job if you&#x27;re sick of it. But I don&#x27;t think you&#x27;re tired because you don&#x27;t have time to work on your ideas. I think you&#x27;re tired because you haven&#x27;t found or refined your existing ideas to a state where it will be so interesting to you you&#x27;re working on it even as your eyelids struggle to keep opened. You don&#x27;t have the time for ideas that aren&#x27;t that interesting, but when you have an idea that&#x27;s interesting enough to you, you will find you always manage to find some time for it.
