For me, the biggest influence has been surrounding myself with other wealthy people. To achieve a net worth of $1 million, deliberately reduce the time you spend with people that have a net worth below $1 million and deliberately increased the number of people with a net worth over $1 million. You'll notice several interesting changes:
1) After listening to them talking about $10 million and up business transactions, $1 million won't seem like so much money.
2) As you become an accepted member of the group, you'll start to think of yourself as "one of them," slowly transforming your identity from someone trying to become a millionaire to someone that is a millionaire.
3) Simply by hanging around them, you'll be exposed to more opportunities that can make you a millionaire.
The same holds for making any amount of money. I'm working on achieving a net worth of $10 million now, and to do that, I'm surrounding myself with people that are making $100 million or more. Just in the last 60 days, they've involved me in two real estate deals that should make me $10 million over the next three years. So, I'm well on my way.
