As a kid you were enjoying life as you did not associate ourselves with any image or identity. As you grew you started enjoying the image that you created. Later you wanted more of it. In the pursuit of the identity you lost all the enjoyment in life.
Lose your image. Become null in your head. Enjoy life. The heavy lifting that you are doing right now is temporary and you will retire. People will forget you. Don't look back and feel bad.
You can do your job with 100% efficiency without mentally associating yourself with stuff that boosts your ego. Do and move on.
