1. I wake up at 9, do morning exercises for an hour and eat a
healthy breakfast. After breakfast I read books on acting or
watch education programmes. It’s important to learn. Then
I check e-mails, talk to the manager and agents. In the afternoon
I practise my monologues. I have a light lunch. In the evening
I have a performance. My life is hard work!
2. I get up very early, usually at 6 o’clock. After a quick breakfast
I look through my lesson plans and at 7.30 I go to work. I give
four or five English classes a day. After lunch I go to the library
to look for some interesting material and prepare computer
tasks. Then I’m busy with our drama society. I go home at 5 or
6 pm taking any unfinished work.
3. The alarm clock wakes me up every morning at 5.30. I do
some exercises and have a quick breakfast. I am at work at 7.30.
At 8 we have a meeting to discuss what problems our patients
have and the strategy of the day. Then I examine my patients and
get ready for operations if I have any. In the evening after a hard
day I go swimming. Sport helps me to keep fit.
4. Discipline is the most important factor in a person’s professional
life. Success is the result of many things. Hard work,
brains, careful planning. I get up at 7, go jogging, take a cold
shower and have a good breakfast. At 9 I’m at my office. I read
e-mails and prepare for the talks with the partners from different
companies. We have lunch at 12.30. After lunch we usually have
meetings of the staff to discuss our plans. I go home at 8 pm or
later.
