Remember, every professional was once an amateur, and every master started as a beginner. Ordinary people can accomplish extraordinary feats, once they’ve routinized the right habits.
Robin Sharma, "5am Club", Harper Collins
If you spend a moment and ponder on who you really are, you will begin to realize your true potential. You are a daughter or son of God. Literally, His children is what we are. That means, our potential is to be exactly as He is. Think about that.
Granted, it will take a lot of time, or however duration is measured in eternity, to reach that potential. However we can start down that path now. It may seem a daunting journey but focus on one step and then the next.

And this potential is not solely limited to things spiritual. That potential also includes things academic, things mental, things professional, things physical, etc., even mastering EVERY SINGLE THING.
But it takes practice. It takes repetition. It takes study. It takes diligence. It takes smart choices. It takes discipline. It takes focus. But we can do it. It's in our potential.
It is up to each one of us to actually start moving, or desire to start moving.
