Hard work is the most important aspect as ‘hard work beats talent when talent does not work hard’. It is always important to work smart. Applying your efficiency in a well planned order, it gives work a better recognition.
The given targets are always difficult to achieve but is not impossible. Try to divide your work in a stipulated time so that you can review and bring out changes if needed for improvement.
If an employee is punctual about its timings and takes care of its deadlines, the person is known to be professional and hence likely to be known for good work ethics.
Its always great to raise your views and be opinionated about anything. In professional environment, which is competitive and makes you learn a lot it is always better to give your judgements in a subtle way.
Always be self motivated, never divert yourself from your goals specially work goals to be precise. For self-motivated people it requires minimal direction from their supervisors.
