This statement is profound on many levels, such as:
1. you alone will be judged for how you live it
2. you alone are responsible for the results you obtain
3. you alone will be blamed for any failures.
What your life is and becomes, what you contribute, who you spend time with, and how you choose to employ the days of your life are ultimately your responsibility.
Let's consider the topic of success. One of the greatest failures a person can make is trying to succeed according to someone else's definition of success. Life is too short, too personal, and too important to waste climbing someone else's ladder.
This is why I teach people to "customize" their success; to determine exactly what it is they want to do and accomplish with the days they've been given. (Of course, as believers we know that this should be done through prayer and a diligent seeking to be obedient to the call of God on our lives. Still, it appears there are huge swaths of territory open for us to decide upon our particular paths within the boundaries of God's leading.)
So what do you really, really want your life to be like?
What dreams have you nurtured deep in your heart for too long now?
What do you truly want to accomplish?
Who do you want to be as a person?
What do you want to be known for?
If people had to sum up your entire life with just one sentence, what would you want that sentence to be?
When you look back on your life, what will you most regret not doing if you don't get started on it soon?
Don't waste another moment. Go after your own custom version of success with everything you've got. After all, only you can do what only you can do.
