The interaction of workers from different cultural backgrounds with the host population might increase productivity due to positive externalities like knowledge spillovers. This is only an advantage up to a certain degree. When the variety of backgrounds is too large, fractionalization may cause excessive transaction costs for communication, which may lower productivity. Diversity not only impacts the labour market, but may also affect the quality of life in a location. A tolerant native population may value a multicultural city or region because of an increase in the range of available goods and services. On the other hand, diversity could be perceived as an unattractive feature if natives perceive it as a distortion of what they consider to be their national identity. They might even discriminate against other ethnic groups and they might fear that social conflicts between different foreign nationalities are imported into their own neighbourhood.

Working around the whole painting, rather than concentrating on one area at a time, will mean you can stop at any point and the painting can be considered "finished." Artists often find it difficult to know when to stop painting, and it can be tempting to keep on adding more to your work. It is important to take a few steps back from the painting from time to time to assess your progress. Putting too much into a painting can spoil its impact and leave it looking overworked. If you find yourself struggling to decide whether you have finished, take a break and come back to it later with fresh eyes. Then you can decide whether any areas of your painting would benefit from further refinement.

A job search is not a passive task. When you are searching, you are not browsing, nor are you "just looking". Browsing is not an effective way to reach a goal you claim to want to reach. If you are acting with purpose, if you are serious about anything you chose to do, then you need to be direct, focused and whenever possible, clever. Everyone else searching for a job has the same goal, competing for the same jobs. You must do more than the rest of the herd. Regardless of how long it may take you to find and get the job you want, being proactive will logically get you results faster than if you rely only on browsing online job boards and emailing an occasional resume. Leave those activities to the rest of the sheep.
