Avoid illfeel

The first day in learning activities at school.
I don't feel fresh in my first day of learning activities, cos there is no time to take rest during the holiday, so I get sick. Actually there is vacation but I don't have holiday time.
I remember on my duty that I must have spirit to serve, share,and give my knowledge to my students, and educate them as well. These duties encourage me to be great people. So I have to throw away my bad feeling. In this case I'll give you the way to do that:
1. Make ourselves happy
2. Make our students enjoy the teaching learning activities.
3. Do our duties without hoping to get compliment.
4. Don't hope thanking from someone after you do something.
5. Do anything in the name of Allah.
I have tried to do that, the result I enjoy my job, my students enjoy the teaching learning activities process, and my sickness is away.
That's only my experience.
