No matter how hard I tried.

No matter how long it takes, I will finish the work.

No matter how you look at it , the situation remains the same.

No matter how much I eat, I never get fat.

No matter how much you eat, you never gain weight.

No matter how hard you try, you can't change the past.

I couldn't shake off the lethargy no matter how much I slept.

I couldn't get through to him no matter how hard I tried.

No matter how you look at it you're a beautiful, ill-fated woman, the heroine of a tragedy.

No matter how hard I try, I always wind up making a mess of things.
