Opportunity
Life doesn’t guarantee a living. It would be nice if it did, yet it’s more about opportunity than a guarantee. You might make a living running a business. It’s risky. You could end up with too little profit to survive well.
No Traction
You keep trying, but nothing works well enough. You make small, incremental improvements, but far short of success.
Persistence
You keep going, fine tuning, making further improvements. Some of your progress erodes at the same time. You’re up and down. You still end up higher, but still lacking.
Quit?
Never! Not ever!
