For sure, 

I don't know what will happen and where I will be when I have reached the end

But for sure, 

I know that while I am still here, there will be no hatred, discrimination and all things bad I will say and do that can hurt other living being

At least for sure, 

I sleep better at night knowing that I am only doing good things and have done my best so far

In this life that is only too short to not live it to its fullest with joy and happiness

Peace!!!
