Serious help required : ca

Hello EveryOne... Need A serious Advice.. Though it will take some valuble times of you all, but may give me a right path.. plz advice .. I am already 27 Year old.. In Coming August I will be 28. I am a CA Inter & CWA Inter..... I left studies completely 3.5 years back as I had to work. I cleared CA inter when I was 22. I was working in TCS with average salary then I joined Capgemini. For initial period it was good as I got a secure job.. But slowly I realized that I made a big mistake by leaving CA. i was not getting leave for attending exam. So I took a courageous decision to leave my job. 4 months I need to give good effort to cover whole syllabus.. Now I am preparing for my CA, after my coming Nov exam I will start working again.. But this time no more MNC... I want to work in normal pvt co or good CA firm as they give leave for exam. I will keep on giving my exam until I success.. Am I doing the right thing, i am a bit tensed bcoz increment in MNC was good in compare to pvt co or Ca firm. I am losing lots of opportunity bcoz of this decision... Am I correct? Now I have finally decided that I will not quit CA till I am 35 years old.. Its risky bcoz by 35 I wpuld have got a good package for my family. I will marry at 31 but will continue CA if i dont clear b4 that.. Atfirst I thought it was a silly decision... Then I thought that this decision will though ruin my life but may help my upcoming family members.. I want to run my own CA firm after I clear my exam... Overall is my decision right??? I am a bit depressed.. Till now I dont have any girlfriend, i dont drink, no bad habits.. i belong to a middle class family... This decision may give me a bit less earning for few years but I hope it will make my future strong... I dont know any qualified CA so i cant discuss my situation with anyone neither I know does my sacrifice worth it... Will it help me..
