Is there any idiom / expression or proverb in English which can imply the situation that someone can manage their own affairs in rather severe conditions?
a) I'm going to go abroad for a while? Perhaps England! b) Well! Do you know English well? a) I can manage my own affairs.
a) Mom, I have made my decision! I've decided to live alone and rent an apartment for myself! b) So can you afford it son? a) I can manage my own affairs.
In my language, there is a proverb which conveys the same message in both cases above and so many other similar cases, but I don't have any idea which expression or idiom or perhaps proverbial phrase can do the same thing!
Some English equivalents that I have found in translation pages are as below:
- I can shift for myself.
- I can fend for myself.
- I can get along by myself.
- I can paddle my own canoe.
I don't know if they work in this sense of natural English! If they are alright, please let me know; otherwise, please tell me how shall I indicate the meaning in my question in a natutural and idiomatic way.
