1. Fun should come first

Life is too damn short to work so hard only to find out in the 11th inning that you didn’t have enough fun. I built a hugely successful real-estate business full of productive people because everyone knew it was the happiest company in town and we all wanted to be there.

For every dollar I spent creating fun, I got a 1,000% return. When I sold the The Corcoran Group for $66 million, I was surprised that all of our fun expenses totaled only .04% of total expenses. Based on what it bought us, I thought for sure it was more like 50%.

2. Be obsessed

You have to be obsessed. You have to be all in, all the time. So obsessed you lose the concept of time. The greatest people who have walked this Earth are those who are obsessed. They don’t drink the Kool-Aid, they swim in it and do a backstroke in the Kool-Aid.

3. Write goals five times a day, every day

I believe in conditioning my mindset and belief system by writing my goals out five times a day. I set reminders on my iPhone and never skip a single day. This helps me condition the mind, and reformat my thoughts to continually focus on my dreams and goals.

By writing every day, I force my mind to cancel the noise, distractions and random thoughts in order to focus intensely on my dreams and goals. Try it for a week and see for yourself how powerful this technique is.
