I made a conscious decision years ago not to measure myself against what others are doing or accomplishing. Everyone has their own set of skills and talents.
My passion is writing. Are there better writers out there? Heck yes, there are! It would do me no good to try to measure up to another's success. Those highly accomplished writers are out there rocking their own talents. I choose to be unashamedly me and continue to grow, learn, and experience so that I can rock my own individual talents.
We all have our own unique skill set and should never feel the need to measure ourselves against someone else.
I am uniquely me and will rock my own talents in my own way, whether it is a slow progression or not. It is my journey to travel and experience.
