Thanks for your response and some wise ideas are motivating too to do Finance. You don't need to have strong math skills for finance. Yes, one need to have thorough accounting principles. I found a smarter way to learn accounts in quicker way. This site
https://www.simple-abc.com offers one to build the accounting skills quickly.
I don't want to join a certificate course, where one gets only a printed doc with not enough knowledge.
So, I am charged now to do finance.
Thanks,
Robert
