help!!

MBA in Finance，accounting，have experience as big 4 Financial analyst for 1 year, but English writing is not good; later tried to switch to accounting, but somehow can not sit still for audit job. Tried started business, failed, already early 40,what should I do? go back to try pass CPA and try again in general accounting job? or become a financial advisor ( insurance, annunity sales). My previous work experiences were all sales, marekting before MBA in finance and accounting. but I think selling insurance and annunity is not a easy job either, purely commission based.  Please help, what I should do?  any advice is welcome.
