Well, if you understand this image, you can understand the figurative meaning that is the one we use today for this expression "to do things the hard way" and which means to make a lot of effort, to struggle, to do everything possible to obtain something even if it takes a long time or even if it is difficult. That is what it means to do things the hard way.
as usual, a few examples so that you really understand the meaning of the expression. The first would be: "We're not going to go out of our way to help her at the last minute, she should have come forward earlier." So here, we say: OK. There's a person who needs help, we blame her for not having warned us before and so we're not going to make a lot of efforts to help her, we're not going to go out of our way, we're not going to make huge efforts to help her, so we're not going to go out of our way. That's what it means.
Another example: "The reception was really incredible. They had to go out of their way to get everything ready so quickly." So here, it's the opposite. They went out of their way to get everything ready quickly, that means they worked hard, they made a lot of effort, they did everything to make this ceremony, this reception, ready.
Last example: "He deserved his good grades, he singapore whatsapp number data spent the year doing everything he could." Here, we indicate that a person spent a lot of time, made a lot of effort to get good results. This person worked hard, did everything to get good grades even if it was long and difficult. So he deserved his good grades and we say that he did everything he could, he made a lot of effort, quite simply.
What I suggest you do now is to work a little on your pronunciation and in this case the sound "in", the sound "in" of the word "main" for example. So, I'm going to pronounce a few words, five, six, seven words that contain the sound "in" and you're going to repeat these words after me, and then, we'll repeat the complete expression. So, here we go. I'll give you some time to repeat.
