I would consider selling things that I don't need, or that are not very important for me in my daily life. Then I would use part of the earned money to invest in something with potential to give me profit.
Yes its a wise idea than to borrow money to someone with interest. i would also sell the things that is not really important, but to prevent that scenario its better to start saving so you will have money to spend incase you badly need it.
Loaning is very difficult and much difficult if you borrow it just to invest to investment that will not give you sure profit. Working while investing is the best way for me.
