Plans and Goals



Plans are taken to achieve goals. Goals may be either short or long term. Generally, long term goals can take about three to five years to achieve, while short term goals are reachable in a year or so. We set goals only when we plan what we want to accomplish. It could be as simple as cleaning the house or finishing an assignment or as complex as transforming a developing country into a developed one.

A plan needs to be written. A written plan provides a visible objective to work for. An example of a written plan is a family budget. A budget shows where the family is financially, how much the family is currently spending, and how much the family can spend according to the current income.

The primary ingredients necessary to develop a plan are goals. Plans are generally divided into
1. short-range plans, and
2. long-range plans.

Short-range plans are basically day-to-day occurrences.

Long range planning is very important. Everyone has a responsibility to plan well, to have good sound objectives, and to achieve success. There should also be some specific goals developed for the use of surplus funds. We should also be clear about how much should be invested and how much should be set aside for domestic wants?

Future income should not be depended upon. It is also important to be moral while achieving the goals. It is necessary to monitor that family is not trapped into anything that is unethical, immoral, or dishonest. In addition, there should be a family contingency plan in the event wealth is lost due to unforeseen disaster.

Dressing Right for The Interview

"Although proper dressing by itself will not get you the job, a poor dress sense may exclude you from further consideration," warns Gerry Ditching, managing partner of Filgifts.com. Besides, given two equally good applicants, the company may choose to hire the person who is dressed more professionally. Here are some tips to give you a headstart.

For MEN:
Long-sleeved shirt and dark slacks. White is still the safest and the best color for shirts. The colour is also appropriate for our tropical weather. Also acceptable: pale shades such as beige, blue, and other pastels.

Tuck in the shirt and do not roll up the sleeves. Never wear a short-sleeved shirt to an interview or any business purpose. Wearing a short-sleeved shirt will destroy your executive image.

Ties. Optional. But if you do wear one, choose a conservative....

Besides, given two equally good applicants, the company may choose to hire the person who is dressed more professionally. Here are some tips to give you a headstart.

For WOMEN

Three-piece business suits, blouse and skirt or slacks, and cardigan twin-sets. Sleeveless shirts should be rejected. Short-sleeved blouses are okay when they are tailor-cut or have features such as a sports collar or double breast design to create a business-like look. Skirts can either be long provided it does not create a Cinderella or barn-dance look or short where it falls no shorter than two inches from the knee. Nothing too revealing, please!

Panty-hose or stockings. A must for professional grooming, but nothing with overly fussy patterns. Bring an extra pair, just in case the ones you are wearing run.

A final variable can’t change from its initialized value. finalize() : finalize() method is used just before an object is destroyed and can be called just prior to garbage collection. finally : finally, a key word used in exception handling, creates a block of code that will be executed after a try/catch block has completed and before the code following the try/catch block.
