I believe we reap what we sow. What we are reaping today was something that was planted/fed/sown 6 months ago, or maybe 6 years ago.... the time doesn't matter. What matters is today, and today should tell us to keep grinding, keep working, keep doing that THING.
The THING should be your most valuable item/list/process. The THING is what you want to hold 6 months from now...
What can we do today that supports tomorrow? = Personal discipline. Then ask the same question tomorrow :)
Small choices add up for sure...
Music doesn't happen over night. Today is the accumulation of daily/weekly/yearly practice!
