My dream job, is to be based in Bora Bora earning 4 times the salary I do now, and only having to fly every Shrove Tuesday in lent! Alas, even if that job actually exists, I am too lazy to actually embark on pursuing it.
Therein lies the problem. How do know this is a dream job? Have you done any flying to see if it is something that you really do enjoy and are competent at. Have you researched the training requirements for all the various necessary licences and ratings. Have you researched the costs and time requirements involved. Have you researched the employment prospects and realities of the career path that you are interested in? Have you researched the job prospects at various points in an economic cycle? Have you researched the attrition rate of prospective commercial pilots and the reasons for that attrition? Have you a realistic fiscal plan that would enable you to fulfill this ambition?
A good pointer would be to do some in depth research. You can start by reading these forums. Whilst far from being the holy grail, they will give you a good insight of the realities people face over and over again, each and every day. Look at the regulatory websites that will state the requirements for basic licence issue and the medical standards required. If it begins to depress you, then look at the training school websites with their rosy predictions and pictures of happy smiling uniformed young people standing next to a lovely jet and wisely wearing quality sunshades as they point meaningfully into the distant sunny skies.
This is an industry that will always need new blood. There are formulaic requirements to be achieved but no particular formula that would enable an individual to achieve them. As an individual your personal circumstances, achievements and goals are either an advantage or a handicap and how you use them to your advantage or overcome them as obstacles is largely down to you. It is also an industry that attracts a huge volume of interest from the the unrealistic dreamers, through to the wealthiest, luckiest, healthiest cleverest and most determined of individuals.
Whilst the country needs more scientists, engineers and entreprenuers and places a priority on recruiting and fostering those types of occupations, there is absolutely no shortage of people wanting to be airline pilots. So much so that people will actually pay to do what was previously a salaried job. The financial risks inherent with this industry have always existed, even for the most successful. Historically those risks became a shared one with the employer. These days that burden has in many cases now shifted totally onto the candidate. Even the flow of employment that normally comes from those at the top naturally retiring, has been all but stopped by statutory increases in the retirement ages for pilots, by anything up to 10 years! A situation almost unique to this one industry.
If this is something you decide is a driving ambition for you. If you are medically fit. If you can find a way to finance the training. If you have a backup plan for the likelihood that there will be no job at the end of that training. If you accept that the industry (even for the most determined) is a very large and slippery pyramid that only begins to work for those near the apex. If you accept that it is a road littered with the corpses of the casualties. If you accept that the romance of dreams will very quickly change to the harshness of reality. If you accept that no matter how rose tinted those expensive aviator sunglasses may be, they will not protect or shield you from these realities. Then yes go for it. But first, do research and do a lot of it!
Sorry if this all sounds a bit brutal, but the truth is, it is a very difficult road for so many reasons, and despite the fact that many happily embark on the journey skipping along it, very few get to the end. The resources you will need in order to stand a chance are, money, luck, health, money, luck, determination, money, luck, ability, money, luck, personal achievements and of course money and luck.
If you cannot see anyway of doing this, then you are either correct and would be wise to give up, (or join the rosy specs mutual support group RSMSG.) That, or you are simply not trying hard enough at the first obstacle. Start reading, start researching, see if you have ability and actually enjoy flying.
