This is called persistence. I agree with you that if you work confidently and persistently in a certain direction, then over time you will definitely achieve the result. I have seen many examples where persistent people have achieved better results in companies compared to more intelligent but volatile people.

Everything changed here thanks to one reform. Previously, old professors could research the same obsolete topic for decades and receive government funding for it.

If not, he is free to look for money elsewhere, for example, from a private business.

I wish you success in your new endeavors and you will achieve it for sure!
