How much quran should I recite each day?

Is it ok for me to read 1 ruku everyday or is that not sufficient? I used to read quran often, at least 3 ruku a day and tried memorising new surahs and preserving these memorisations. But ever since I was afflicted with OCD and wiswas I have abandoned the quran and I barely read it. I just feel too lazy and demotivated to read it. My wiswas is to do with najasah and doubts about missing the pillars of acts of worship I feel like coming back to the quran by reciting at least 1 ruku a day and then gradually increase the recitation of the quran.
