Unlike many people, I have always wanted to do what I am doing (if you ignore my very first few years of my life when I wanted to be Noah, but that hinted my early interest in all the animals). From what I can remember (and I am sure my parents have a slightly different version), when I was about 4 getting given a book on dinosaurs from my uncle on dinosaurs and my fascination grew from there. An aunt, who lives down in Dorset, took me to the Jurassic Coast shortly thereafter and I found my first fossils. Lots of belemnites.

So for people interested in getting into palaeontology, how do you go about it?
This is the most important of all requirements for modern palaeontologists. There are undoubtedly exceptions (e.g. Jack Horner) who never went to university, but the field has come a long way and everyone has at least a masters level degree, and most have PhDs. This is definitely a requirement as for the academic route into palaeontology (preparators generally require less academic degrees, but much more experience to get a job). As such be prepared for a commitment on the same level as medical doctors in terms of time at university. Before you get there, the focus is heavily on sciences. For A levels, there is a focus particularly on chemistry and biology required for university, and knowledge of maths and physics is incredibly useful. Surprisingly geology is not required! As for degrees at university, I know people who have gone through biological sciences, zoology, geology and natural sciences at various universities. Importantly, it will be picking topics and projects that are palaeontology related throughout the degree that will set you up better for masters or PhDs which are looking for specific experience in those areas.
This applies at any and all levels really. If you are enthusiastic about it, do some research into who is doing work in the things you are interested in. Most large universities have geology or biology departments with at least one palaeontologist. Even if there isn't a palaeontologist, there is probably someone doing evolution based studies that would be worth contacting to see if they have volunteer projects. Museums are much the same. In Bristol, I know several summer projects ended up as publications. Remember, for university applications, they are looking for people who are passionate about what they are doing, and for higher degrees you need to be able to show this. If you are interested in doing field work, most large US and Canadian universities and museums do field work every year and often are looking for enthusiastic volunteers. The best ones you shouldn't have to pay for besides transport to the site and back.
It doesn't have to be scientific papers, but that does help. Read the news, find the palaeontology stories (the BBC science has lots but there are other sources out there). If there are stories you want to read the science, look for the paper. Some are open access so anyone can read. If they aren't, contact the author. Usually they are very happy to share their papers. If not, Facebook has groups that share papers, and there are places like researchgate.net and academia.edu that may also have them. You may also be able to find them on places like Sci-Hub but there are ongoing copyright cases associated with that source.
Get into the field
Something that I've said many times previously, and am incredibly passionate about, go look for fossils! In the UK there are loads of amateur groups that go collecting, great websites for finding out where to go and what to look for and even guided trips (e.g. UKAFH). I suspect there are many such groups in every country. Not all palaeontologists are field palaeontologists, but it helps if you can put fossils into geological contexts which you can only get by going into the field.
If you are a parent and you kids love fossils
All I can do is encourage you to encourage your children. Take them to museums. Take them fossil hunting. Most kids grow out of their dinosaur phase. Some of us don't. Even if your kids grow out of the phase, many people maintain that fascination in dinosaurs and may develop other useful things like reading news/science, a love of the outdoors, or just be incredibly grateful that you didn't force them to do something just because you thought science/palaeontology doesn't pay well. You can make a living from it, and many do. It isn't an easy career, and there is undoubtedly a long time in university, and a long time after where you have 1-5 year contracts and a lack of stability. The support of my parents let me do what I love, and made it a lot easier every step of the way.
At the end of the day there is no "right" way to get into palaeontology. There is no time limit, no restrictions on when you must study palaeontology. If you love it, go for it.
