2. Spending too much time on doing your personal work:
Office is not a place to bring all your personal works and start doing it in office by giving them the first priority. It can be agreed that, some days at office you will be having very less office work as you would have already completed your office work by finishing it during the past days whenever you were free. But, if you find any such free time at work even after completing all your professional tasks, it will be your responsibility not to engage yourself in any of the personal activities for a long time by chatting over the phone, gossiping with other colleagues on non-office related issues, shopping online, checking social networking sites etc.

If you really don’t have any other tasks at workplace, then try helping your colleague for some extent if she or he is in real need of it and struggling to schedule time for each work or else, you can start planning foe your next assignment or think of an idea that can help develop the profit of your company.
