I just want to know the average salary of an insolvency lawyer after, say 2 or 3 years? Also, about how much may they earn in the first year? And how much may they earn in more advanced years? I know your salary can considerably vary from place to place but I mean in more broad general terms.
Not being greedy or anything I just wanted to know and I couldn't find anything on the internet.
Also, what sort of subjects would it be helpful to be good at if you want to pursue this as a career?
Thanks.

I do not know the country you are in, since they are called Bankruptcy attorneys in US, I will have to assume you are not in US.

It is a lower paying field normally, and are they working for a firm ? Or opening their own office. If they open their own office most likely they may lose money the first 1 or 2 years, with costs of operation more than income. Some work for for large firms at 40,000 US.
But can vary greatly

A lawyer's salary varies a LOT from place to place, firm to firm, the times you are living in, and how well you did in law school. That's just for starters. There is no point in even trying to find out. I've known lawyers right out of law school who had offers that were double other offers.
You are 13. There's a famous saying on a wall at Harvard Law School (quoting one of the US Supreme Court Justices) about what studies a lawyer should pursue as an undergrad, and it says that you should study everything except the law. A great lawyer has a vast array of general knowledge.
