The principle is: Be observant for things that "announce" themselves as need of repair*. "if you fix 100, things like that, your life will be a lot different."
People tend to consider those [routine] things trivial...
the daily routine items like getting up, eating breakfast, brushing your teeth, etc. Claim : Those are the things that constitute 50% of your life.
... they think "well, they're mundane and I don't need to pay attention to them."
Exactly Wrong:
Evidence: - The math: "100 adjustments to your broader domain of being and there's a lot less rubbish and there's a lot less rubbish around and a lot fewer traps for you to step into."
Once you've got your mind and your emotions together, and once you're acting that out, then you can extend what you're willing to consider yourself [the limits of your being], and start fixing up the things that are part of your broader extent [external].
On the temptation to try and fix things you're not ready to fix...
Story 1... evidence
"Imagine you're walking down the street and there's this guy who's like alcoholic and schizophrenic and has been on the streets for 10 years, he sort of stumbled towards you. Now, that's a problem!"
It would be good if you could fix it, but you haven't got a clue about how to fix that.
You just walk around that... go find something that you could fix.
Why avoid trying to fix a problem like that...
If you muck about in that...
(1.) it is unlikely that you'll help that person. (You're unqualified.)
(2.) it's very likely that you'll get hurt yourself.
Deductions:
Analogy: "you don't walk up to a helicopter that isn't working and just start tinkering away with it. You have to stay within your domain of competence."
The key is to start where you can start... Literally: 8_Pq4m24C. i-WCUMXXM. You have to give your mind a genuine aim by specifically asking the question. You've given your mind an instruction and it can listen and act, observe! You will notice things will start to "announce" themselves as needing to be repaired. This act can be done with something as simple as a room, or as complex as a relationship... but practice with something easy to define*.
