"Whether this is the best of times or worst of times, it's the only time we have got " - Art Buchwald
Doing easiest things first: You don't get recognized at workplace just by doing things. Your bosses or clients remember you when you complete the most critical task on time. So before starting any work always considers whether this work is significant or you are doing it because it looks convenient to you. Always remember you have to complete any given task or assignment whether it's suitable for you or not. If you are doing the most comfortable work first ignoring important work you are just wasting your time, and neither your boss nor client will value your work. And moreover, you can't justify your pending work in this condition.
- Checking personal emails and making personal calls: If you check private emails or make personal calls twice or thrice a day, you will create an unnecessary interruption in your work, and moreover, you can't complete your work on time. You have to work after office hours and by and by you will start losing your efficiency. Whenever you are on vacation or take off, you don't want to do official work; similarly, give your 100% while you are in office. To avoid this situation, you can check your emails once a day and limit your call to maximum 5-10 minutes during office hours.
- Hesitation: When I started working in Industry I had to ask many things from my seniors, colleagues, and clients. I was hesitant every time, so I used to delay my work. Many times I got a tongue lashing from my bosses. Finally, I understood I could not survive in Industry if I kept hesitating. Just consider what happens when you wait i.e., you cannot complete your work, you leave office with tension, you reach office thinking about work, you can't think of changing your job, and you have to forget about salary raise or promotion. So if you hesitate, everything will go wrong, and cost of hesitation is too high.
Now consider what happens when you are open and bold
