Daily Duas-what difference do they make?

I have a chart like this but I never use it. My kids have never used it either, we've never bothered to memorize any duas. I have some on my door for entering and leaving, once in a blue moon I will read from them to make dua. People who grew up muslim learned these since they were kids and they roll off their tongues.Other kids are suprised my kids don't know them. I guess I've never really bothered with them because I don't see the point. I mean of coure its to worship Allah but what difference do they really make in your life. Are people using them just out of habit? Do they think they make a difference? Do they feel they are like insurance? Do they do it because everyone else is doing it? I don't know why but I can't get over the idea that these duas are like accessories instead of the main outfit which are fard prayers but I also feel that way about sunnah prayers and dhikr. I think I am like the bedouin and just want to stick to the fard and leave off the rest. Conversion was hard enough with all its changes. I feel adding more even after all these years feels like a burden. So tell me if I'm wrong! What difference does it make???
