One of my all-time favorites is Essentialism, by Greg Mckeown, the book completely changed my life, the biggest thing it teaches you is how to remove the non-essentials from your life, the quote "less is more" is referenced because it means that by getting rid of the unimportant things in your life you actually have more time and better time to do the things that actually matter, it explains how most people believe that being "busy" is productive but it is actually not, only when you learn the mantra that If you don't prioritize your life, someone else will. can you truly be Essential.

I'd recommend @Scott Trench's book, Set For Life, the entire Mister Money Mustache blog, and the BP podcasts to help get your mental wheels turning in the right direction.

Of course, that assumes that you are willing to spend the mental energy to manage more doors and tenants or managers.

Again- they have prioritized their money in such a way that the $50 cost of being late is worth it to them.

The benefit being you can prioritize great schools and a suburban subdivision environment and still be a short drive to the city for night-life, culture, etc.
