This is the absolute best advice for someone starting out. In fact, I’ve lived by it for the past 9 years.
Here are a few examples that come to my mind of this thought process in action:
Don’t have money to hire a web developer? Use WordPress.
Don’t have money to buy a camera? Use your phone.
Struggling with 3 kids and can’t feed them? Make a deal with a restaurant (for example, do video or web dev to barter).
Can’t afford gas to get to where you’re going? Get a bike at a yard sale, take the bus, etc.
Your parents are broke, you’re broke, you didn’t do well in high school, but you want to go to college? Use websites like Khan Academy, Udemy, and even YouTube to learn (for free or extremely cheap).
One of my favorites.. don’t have the cash to afford a personal trainer? Make friends with someone who’s really fit and is down to work out with you (on a schedule).
Want to travel full-time around the country? Work at campgrounds (work-camping). My wife actually did this in Raleigh, NC.
A very simple, but real example… Can’t afford to buy a pen? Borrow one. And give it back. That way you can borrow it again.
Don’t have money to buy the audiobook or physical book? Go to the library.
I know these are straightforward.. but a lot of people miss out on opportunities in front of them because they think they need the resources to make it happen.
