The most difficult skill to master for many real estate professionals is learning to deal effectively with objections. You will know you've mastered this skill when you begin looking forward to answering buyer and seller objections.
The best catalyst for success in any undertaking is diligently practicing the task(s) and activities you are weak in to the point where you become proficient at it. In other words, do it over and over again! You cannot hit the ball thrown at you (objection) if you don't swing the bat. Striking out is never seen as failure to a pro-baseball athlete. It is essentially viewed as a step closer to hitting that home run.
Hence, your attitude determines your perception and your perception determines your reality.
