I am normally tired only at the end of the day especially if I have been active and running around the whole day, but it is a pleasant kind of tiredness and with a refreshing bath you are back to being energetic and active once again...

I am tired when I have to defend my self, and I am tired of hearing promises when there are mot met.

How true. It is a pleasant kind of tiredness. In your case Boredom never approaches you.

When work is considered as worship, there will not be any boredom or tiredness; but it will rejuvenate us, and fill our mind with the fullness of satisfaction; irrespective of the time of work.

A famous celebrity who is a worholic was asked , ' you are always on work. When would you relax?'

His reply was " I relax while doing my job. and there is mo better way to relax while working."

Boredom makes me tired too as it happens when we do things repeatedly in which we are not interested we get tired.

I am not tired of working even for 18 hours a day but I get tired of waiting for anything unnecessarily.  

That is the point. Waiting, in the view of a person who finds pleasure in WORK is nothing short of losing one's most productive moments going into drain.

Many a times, I do not feel tired but feel fatigued after prolonged work hours. 

But that tiresomeness and fatigue are the part of the game that keeps you moving.
