Some people have given solid advice here on financial restrictions, so will focus on the 'fire for building' part.<p>Recently listened to a podcast of Tim Ferris, where he interviewed Tony Fadell - who built the iPod, iPhone and Nest. In it, he makes a serious case for getting bored. He explains how he uses it to drive new ideas, such as how it helped him get the clarity of mind to get the idea of Nest, and how afterwards he's done the research for his current problem - one of plastics.<p>"Get the time to get bored. Spend three, six months if you can, or at least two or three weeks outside of that. Get bored. Just put away all of your things. Maybe go clean up the garage or whatever it is. Right? Through that, you’re going to start to think differently. You’re going to act slightly differently and your mind might open up to other sources of inspiration, other problems, other things where you start to go, “Oh, now I see differently.” I’m not just going to go run to the competitor because I understand the space and run to the competitor and go work for them because they’re going to give me a better job. But I want to go do a whole different thing that I want to learn about that’s going to challenge me so I’m not just checking in every day and doing my work, but I’m actually growing through that."<p>Listen to it here: <a href="https://tim.blog/2019/12/23/tony-fadell/" rel="nofollow">https://tim.blog/2019/12/23/tony-fadell/</a>
