A customer can read through insencerity. So you need to be sincere in all that you do, and that means examining if the work that you do is really what's best for you.
If you wake up each day with no motivation to go back and do another day at that place, then change. It is your choice to go and find something that fires you up each day. Only then can you give sincere and meaningful service to others.
The other bonus is that you are doing something which keeps you alive and makes you feel glad to be a part of this wondrous universe.
So....go and find what you want to do and do it to the best of your ability, then you are serving both yourself and the world.
