I like to say this one is an oldie-but-goodie since we see it so often.
The great thing is that each time you read it, it fills you with feelings of potential and possibility.
Deep within man dwell those slumbering powers; powers that would astonish him, that he never dreamed of possessing; forces that would revolutionize his life if aroused and put into action. -Orison Swett Marden
I’d suggest you print or write this one out & put it somewhere that you can read it daily. The positive reminder will set you back on-course in case you’ve forgotten your purpose.
