The freedom to do your own thing ends when you have obligations and responsibilities. If you want to fail yourself - you can - but you cannot do your own thing if you have responsibilities to team members.
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.
Winners embrace hard work. They love the discipline of it, the trade-off they're making to win. Losers, on the other hand, see it as punishment. And that's the difference.
All winning teams are goal-oriented. Teams like these win consistently because everyone connected with them concentrates on specific objectives. They go about their business with blinders on; nothing will distract them from achieving their aims.
