We're getting a little deep into the rabbit hole there :P

Ignoring time, which is much more difficult to stick into an analogy. It's really pretty simple, look for 'deals' in your day to day life, set that money aside, think of it as an 'investment' then.... once you have that (highly addictive) stash of funds..

Use the same mentality that allowed you to find those deals to find investment opportunities..

It really has to be a hobby at the start, was for me anyway, I mean the savings from toilet paper aren't entirely life changing :P But the mindset is incredibly valuable... :D
