never stop learning and developing．You should read and keep up with events．You should spend time with your family and take care of your myriad of daily chores． At work，it’s not enough to be qualified for your job You have to have excellent people skills and problem—solving abilities．Your IQ had better be high，and you should welcome anything and everything new．Commitment and enthusiasm are the bottom line At home，it’s not enough to have money in the bank．There are children to raise，hobbies to encourage and daily routines to organize Contacts between home and the day care center or school are another priority．You have to keep up your friendships and your family relationships．You have to have empathy for everyone around you．You have to have time How do we catch a guilty conscience?Finns in Business asked family counselor Hannu Kuukka from the Helsinki parish services．“A bad conscience comes from conflicting pressures，from the feeling that you just can’t manage everything that you consider important．Frustration and stress are the result．” “Our internalized roles—the role models that we subconsciously follow—also contribute to the problem．Throughout our lives，we carry with us the part we played in our own family．This can be a source of encouragement and support，or the seeds of a bad conscience” What can we do for a bad conscience?“Our failures tend to become exaggerated in our minds．especially if someone close to us verbalizes them．You have to set priority．Couples should decide to gether if one of them is going to concentrate on work and the other on family．The couple is the foun dation of the home，so they have to find common ground，”comments Hannu Kuukka At work，you spend your time with adults，and you can excel in your own field Are you more comfortable at work than at home?This is a common feeling--and another source of guilt．“It is not unusual for relationships at work to be easier and more straightforward than those at horne The everyday life of a family with children can be exhausting．And today，with growing competition and more friction at work，even these relationships have become more difficult．”says Kuukka.

as provided a bonanza of scientific information．It was first spotted 370 million miles from Earth，by an astronomer who was searching the sky for asteroids，and after whom the comet was named Scientists who tracked Kohoutek the ten months before it passed the Earth predicted the comet would be a brilliant spectacle But Kohoutek fell short of these predictions，disappointing millions of amateursky watchers，when it proved too pale to be seen with the unaided eye Researchers were delighted nonetheless with the new information they were able to glean from their investigation of the comet．Perhaps the most significant discovery was the identification of two important chemical compounds methyl cyanide and hydrogen cyanide--never before seen in comets，but found in the far reaches of interstellar space This discovery revealed new clues about the origin of comets．Most astronomers a gree that comets are primordial remnants from the formation of the solar system，but whether they were born between Jupiter and Neptune or much farther out toward interstellar space has been the subject of much debate If compounds no more complex than ammonia and methane，key components of Jupiter，were seen in comets，it would suggest that comets form. within the planetary orbits． But more complex compounds，such as the methyl cyanide found in Kohoutek，point to formation far beyond the planets；there the deep freeze of space that kept them unchanged
