With all due respect, engineering may not sound easy but with immersion and diligent one can succeed. Success entails hard work. I am a believer of Cynicism. What is gone not necessarily needs to be recalled. If you get another shot, you have to be determined and rely on your self-esteem. Remember not all politicians carries a PHD or MAsters but they somehow or someway did delivered and contributed for their countries.
Petroleum engineers enjoy an unusually high level of compensation and job security relative to the rest of the engineering field. Because oil is one of the most consistently demanded commodities throughout the developed world, and engineers are necessary for its extraction and refinement, there is a demand for engineers around the globe. The industry is moderately cyclical; fields and areas rise and fall along with oil prices, but the general employment outlook for engineers in the industry is solid.
Compensation
According to the Bureau of Labor Statistics, petroleum engineers earn the highest median wage of any engineering category at $108,000 per year in 2008. At the upper end of the pay scale, such engineers earn superlative compensation connected to performance. The one downside to earning such compensation is that it often requires that you move overseas, spend time living on offshore platforms and deal with more inconveniences relative to more conventional lines of work.
Job Security
Petroleum engineers enjoy unusual levels of job security because of the evergreen demand for oil. Although oil prices rise and fall, temporary drops often merely lead to an increased emphasis on exploration and preservation of existing developments. The complex nature of petroleum extraction and refinement also means that there are multiple disciplines within the industry that require engineering expertise. There are opportunities for horizontal and vertical career movement within the industry--choosing different specialties, enjoying promotions and moving to other developments.
Low Supply of Graduates
Because of the challenges associated with being a petroleum engineer and the limited areas where you can work--oil workers can only live where the oil is located--relatively few graduates pursue the field, despite the high compensation. This means petroleum engineers can enjoy a long and secure career within the industry, no matter where you go. This provides you relatively strong bargaining position, because it's inordinately challenging for employers to replace you.
