You must be aware of what's going on in the world, well beyond your own borders, to become a successful professional with significant responsibilities. Set aside a specific time each day to read. Only 30 minutes a day covers an amazing amount of reading over a year. Always carry a book or magazine with you to take advantage of all the times you have to wait for someone or something. Finally, set a strict limit on TV watching and stick to it.
Television is addictive and usually the biggest deterrent to reading.
A pleasant, friendly personality will gain you many friends who will not only make your work environment enjoyable, but will teach you many valuable lessons as a result of their experiences, both successful and unsuccessful. Colleagues who are good friends are good for sounding out new ideas, evaluating results, troubleshooting problems, and listening to trial run presentations. Above all, develop a positive attitude. Someone who complains, gripes, and is constantly finding fault poisons the atmosphere of an office and quickly becomes unpopular. If things are really that bad, change jobs.
