I am.42 years old working in a construction company last 1.5 years . My total work experience is 16 years .My reporting boss very good person and always supportive to me and guide me .But I always feels that I am not able to perform the way he wants. I want to perform . kindly guide me.

Ans: Hi,
Since you have been in the same company for 15 years , please speak with your boss in private and let him know that you are not very comfortable with his approach.If that is not working try and speak with your super boss . Meanwhile start searching for a job and start attending interviews aswell. It is much easier speaking to your boss when you have a backup offer in your hand.,

Ans: Hello

Managing boss is a skill that we all need to learn. Suggest you learn this skill.

You said you are adamant, that's a good awareness and also acceptance so start working on that...try and change your adamant nature to lme of more accommodation one.

Lastly, sit with your boss, make him your companion, ask him for feedback and support and most important also share your approach and try and strike a common ground.

Be assured you will see positive change.

All the best.

Ans: Hello

Now that you are aware of your situation...accept it as is and start working on to be your natural normal self... believe in yourself and most important don't fear losing job. Imposter syndrome happens because we fear losing things in life.

All the best in your new journey.

Ans: Hello Mr Arshad!!
" I am in consultancy business for 20 years and have sufficient work, good clients, excellent relationship with employees and employers as well. "
Isn't this an amazing achievement, congratulations!!
I really am failing to understand your problem here.

I am taking this statement of yours, "But could``t performed well in execution. However some well wisher suggest me to prioritize my tasks and activities. Despite the continuous efforts, it couldn't done."....does this mean that you are not good at getting all your tasks done on a day to day basis?
I am assuming this and asking you to check if you are packing too many things in your schedule and hence at the end of the day you are feeling a sense of not having performed well!!
In order to feel a sense of achievement and a feeling of having executed the day well, you need to schedule your day, setting a time for each activity .Let this list be written down on a white board and let this be in your line of sight always, this will give direction to your day.
Also check( and I am repeating myself here) if you are packing too much into your day, you have only 24 hrs in a day, you can only do so much. Don't be overwhelmed. See if you can put all your tasks under the following categories-

This is called the Eisenhower Matrix-
First Quadrant (upper left): urgent and important.
Second Quadrant (upper right): important, but not urgent.
Third Quadrant (lower left): not important, but urgent.
Fourth Quadrant (lower right): neither important nor urgent.
Do the tasks in quadrant 1 first.
Decide on when to deal with the tasks in quadrant 2.
Delegate the tasks in quadrant 3.
Delete the items in quadrant 4

Hope this helps!!
Happy managing your time well.....all the best!!
