I would like to increase the noor in my heart and change my aklaqh, to be a person with a pure heart and to become optimistic.

I am used to read duas and zyarat everyday, but I just realised that doing all these, without a good aklaqh, is not efficent.

Please, do you have some advices that I can do. I try but still disturbed by shaytan.

Alhamdulillah you have realized. This is also a blessing.
Try to listen to lectures available online.
My Ramadhan 2019 lectures will help you InshaAllah.
Other thing that is important is your relation with others, behaviour,
positive thinking, doing work on it's time.
These things help you InshaAllah.
