Studies have shown that the way a person practices is more of an indicator of improvement than the amount of time they spend practicing.
If you want to get better faster or take your company to the next level more quickly, go back through your old weddings and evaluate what went wrong, what you could have done better, how you could have delighted the client even more. Going forward, take these notes within a day after a wedding is over. Write them down so you can refer back to them later. Have your team do the same.
This really is the secret sauce. You will be a lot further down the road in ten years if you review, critique and evaluate your past work on a consistent basis and make the appropriate mid-course corrections than if you just spend the next ten years only relying on the improvements that come from repetition alone.
