I follow three rules: Do the right thing, do the best you can, and always show people you care. You’ve got to make a sincere attempt to have the right goals to begin with, then go after them with appropriate effort, and remember that you can’t really achieve anything great without the help of others.
An agent won't help you get drafted higher, won't make you win more games, and won't make you faster or stronger. They all say they can, but the people who do the drafting don't talk to agents. They talk to coaches, they watch film, they talk to the people who've worked with players. They don't talk to agents.
Your neighbors will make judgments about you based on how your lawn and house look, and people who see you passing will judge you based on how clean you keep your car. It's not always fair, but it has always been true. Appearances matter, so make yours a good one.
