Yes i agree with you,steemit is a school. A person who fail to learn is a dead person while he is still on earth,"like a walking corps".
We can be good or the best in our niche but in other niche we are a learn. That is how life is,but what i believe is for you to be the best in what you do,create room for challenge and always come out as the best. Challenge helps us to know how good we are and create room for advancement.
That you fail those not make you a failure,at one point in time we have all failure but remaining in that spot where you fail is what make's you a failure. Every successful person have once fail in some area of their life. Remember "readers are leaders".
Keep on learning and creating room for advancement. Thanks
