I honestly don't really know what happens in the afterlife. And I feel I won't know for sure what happens anytime soon either.
I am more focused on thinking about finding happiness in my life and enjoying the small pleasures of taking risks, having fun, and basically just living a good life before it comes to an end. That doesn't at all mean I'm going to be thinking about "oooh what can I do to be happy today". That's called being unrealistic. But there is such thing as trying to find the positives rather than negatives of events that happen in our lives.
Right now I just go with the flow, and make my thoughts and decisions day-by-day even if I have a "plan" in mind, cause not everyday goes according to plan.
I think it's important to use my time wisely while I'm still here.
