We all fight for things. There is always a competition for getting admission at the university, getting a job, or whatever. Thousands of people will apply for the same position. If you are lucky enough, then your resume may be shortlisted. Especially, today there are more opportunities but getting that opportunity is tough too. It may take you a lot of hits. Machines are slowly replacing many jobs. At the same time, new skills are required for a new kind of work.
People may fight for everything, but one thing nobody on this earth can fight for is TIME. It is the most precious thing.
