Hi Rachana,
The statement above is controversial.
---> I feel this sentence is not appropriate to start.
Strictly divide your essay into 4 paragraphs as suggested by Pahan.
Nevertheless, many people do need change. They have no boundaries, no limitation. They accept and welcome changes.
Try to frame your sentences in complex statement structure something like
" However, there are people those who are eagerly willing to face new challenges and there is no limitation in their widespread boundary."For example, these days most of the leading companies encourage their employees to rotate jobs.
I dont think companies are encouraging the job rotation these days May be you can say like this
Nowadays, people hate monotonous job, for example software professionals seem to change their jobs every two years on an average, in order to increase their financial status and also to explore their knowledge in various latest technologiesPeople who do not prefer change falls into pessimistic people while who prefer change are optimistic people. Pessimistic people are static in nature.
Try to avoid repetitive words and get know how to use synonyms.
I hope this information will be helpful for your writings. Good Luck !!!
Regards,
Arun
