- No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other.
Business development is difficult stuff. It takes full immersion of your life. Strategic thinking, internal role playing, constant activity and thorough follow up are all necessary components of a successful career in sales.
I have known people that have tried to have two pursuits at once. Perhaps a job in corporate sales and selling real estate on the side. They are effectively serving two masters. Even the greatest sales people can only be good in this scenario. Also, the resentment you will have for one or both pursuits is inevitable. When you know you are capable of greatness but aren't achieving it, it leaves you feeling empty and this will make you resent your efforts.
Greatness requires a full commitment to a single "master." Unless you're Bo Jackson, in which case the rules, even if derived from scripture, don't apply.
For the past 5 years I have been serving two masters. Soon this will change and I'm very excited to see what I'm capable of with a singular pursuit. It's been years since I've had this luxury.
So, go forth, don't spread yourself too thin and give yourself to one professional pursuit! Let it be something you enjoy intensely.
