I was advised to try my hand at developing on Solidity,
You should first decide what you have in mind when you say "blockchain development". For example I wouldn't call learning Solidity "blockchain development" since the only utility of this programming language is to create useless tokens on token creation platforms.
I think he is talking about any particular branch under Blockchain Development. I guess he feels that urge that Blockchain Development is actually worth it and since he’s a dev already, he can adapt to almost anything.
OP I think you should take courses, platforms like Udemy, Coursera, offer free courses on different topics even programming. Or you can go to YouTube instead and just find a playlist that is like a mini course. Google search will only show you what blogs are saying.
