Start today, and keep going until you reach your goals. Continue on even if you make mistakes. The most important step isn’t starting on Day 1 to work toward your objective. Day 2, the following great day, would be that. Aim for a 50% completion rate if you wish to succeed. Cut your target in half, in other words. This will be effective for objectives like morning running or weight loss.
It’s challenging to cut some objectives in half. Don’t split them in half for those; allow yourself additional time.
