Dear Friend, the desperation from your side to become an efficient and indispensable Executive Assistant to the Chairman/CEO is evident. Have you noticed the spelling mistake in "Chairman"?
It's not a matter of eagerness or urge; a person can become indispensable and efficient. But it requires calmness, caution, maturity, and a cool head. I am sorry to say that right now, you are not cool-headed from the way you asked for advice to become efficient and indispensable.
Planning CEO or Chairman's Tours and Meetings
Dear Nath, while planning your CEO or Chairman's tours and meetings, you have to consider the weather, environment, climate, infrastructure, season, availability of your boss's needs, his likes and dislikes, reading his mind, reading his indicative body language, spoken words, and unspoken expectations.
No job gives you a 100% guarantee or satisfaction, but there is always room for improvement on your side. We must learn from experience and mistakes—both are important. Not to undermine your efforts that you must have taken, slogged, and exerted to your limits, but you let go of the opportunity that has come your way to prove and improve yourself.
Life Lessons in Professional Growth
Things unfold in life—sometimes with your efforts and sometimes with your destiny—both taken together, you yourself are "made." I was in an almost similar role where initially it felt like the sky would fall on me, but with time, I realized that we are all human beings, and sincerity and hard work always pay off—sometimes late, sometimes too late, sometimes not at all. But to every act and effort of yours, there is always a silent spectator—at least yourself—to judge and let you have a good sleep.
Boy, have patience and never ever give up the efforts. If you think your current job is exactly what you wanted from life, you are either in your slumber sleep or do not want to accept reality. No job in the world is crafted for the specific employee. And that's why so many of us are employed—sometimes in the jobs that we like and sometimes in the jobs that don't like us.
Regards.
