Saving Money

Hi Brooke,

I quit my job and decided to become a novelist. I have credit cards debts, which I am paying regularly and am living from savings I have.
I spoke with a friend who said I should take even $100 each month and put it in a savings account, for a rainy day.
In terms of interest, the banks give a ridiculous interest rate these days so it’s basically just taking $100 and putting it away and accumulate it.
What are your thoughts on savings accounts and saving such small amount?
