This is my 1st post and hope you guys won't shoot it down

I am a Vietnamese male, 40y, SPASS holder and have been working in SG since the beginning of 2015. Started as EP holder, changed few companies as EP and now settle in this company but only SPASS with total income around 90K (inclusive the bonus, etc.)
I had tried applying PR 2 times and all got rejected (as the norm). LOL
Now I want to give it a try again with my family (my daughter is getting O-level in government Sec school soon). I absolutely know the chance to get PR is damn slim but post here with a hope that your opinions might be more objective and informative.
How do you think the possibility to have PR as my profile?
Please dont suggest to find a SG girl here though I want to. LOL
Thank you so much.
