Motivating Myself for completing CA Final after a long break of 20 years

I cleared my CA inter around 24 years ago. Since beginning I was very sincere and bright student.After this I appered in -CA final for 4-5 times but somehow couldn't clear.The main reason - I fell prey to a vicious cycle of stress,anxiety,depression.Also, other related health issues overpowered me so much that I could not give exams for some attempts.Seeing the Financial constraints, I got engaged in Coaching Profession for -CA -CS ICWA(Now CMA).Since last 20 years around 1000 student tought by me have cleared -CA Found,CAinter and also CAfinal( Many people do not believe it).My incomplete qualification still hurts me a lot,everytime.Can somebody suggest me How I should motivate myself to to take up Studies again.Inherently,I always feel that I can pass it definitely.But I feel very low to restart it. Hope someone is there to guide me.Jai guru dev.
