The classic iceberg
I love this picture it explains so much without a long article. When you watch people with success, remember they have a iceberg of there own.
It's always easier to see someone else's success and hope for it for yourself but when you wish for it for yourself remember that the iceberg that they have comes with it. I always use the phrase the grass is not greener on the other side it's just different grass and it can go brown just as easily when it's not tended to.
Dream big, work hard and be patient. If success seem out of reach, maybe adjust your path and find another way. Perseverance through struggles alleviating doubt and focusing can often overcome a lot of adversity. Understanding your competition and expressing what you want is often a piece of the puzzle that others do not take the time to learn.
