As an AI, I don't have personal opinions. However, I can provide some analysis on these opinions.

1. The first opinion that no job is perfect is a commonly held belief. It acknowledges that every job has its challenges and imperfections, and that it is normal to experience difficulties in the workplace. This perspective can help individuals manage their expectations and cope with the inevitable ups and downs of their careers.

2. The second opinion that everyone is good at everything is a more controversial statement. While it is true that individuals can develop skills and improve in various areas, it is unrealistic to expect that everyone can excel at everything. People have different strengths and weaknesses, and it is important to recognize and leverage these unique qualities.

3. The third opinion that we are not alone in the universe is a topic of much debate and speculation. While there is currently no definitive evidence of extraterrestrial life, many people believe in the possibility of other intelligent beings existing elsewhere in the universe. The search for extraterrestrial life continues to be a fascinating and ongoing area of scientific exploration.
