The difference between the two is wildly simple: specificity.
“Exercise more” is a great sentiment, but a terrible goal.
If you got down and did 5 pushups, you would have exercised more.
If certain desires of yours seem foggy, and certain loops are still open, break them down into their simplest and most trivial parts.
“Exercise more” becomes:
• Today, after breakfast, download that fitness app my friend suggested.
• Starting tomorrow, go to the gym at least twice per week.
• Starting Friday, run one lap around my neighborhood at least once per week.
These are all pass/fail, measurable goals. A month from now, you’ll know if you’ve successfully stuck to each of them.
When things feel fuzzy, get crazy-specific.
