Sitting, Waiting, Wishing

I have been thinking a lot lately about one's place in life. Are we destined to be where we are or is it completely up to our decisions?
I wanna say that it is all about fate. That no matter what we do, we end up in the same place with the same people. I believe that wherever one is in life they are meant to be there. There is a reason why everything turns out the way it does, I believe. But does that mean that it is predestined? If we might "the one" and go through life with them, was that always going to happen no matter what decisions we make.
Or is it the opposite? Do we miss out on opportunities due to the decisions we make? If I had said that thing when I wanted to, would my life be totally different? Did I ever have the chance at that life or was I always going to end up like this?
There is something easier about thinking that our lives are predestined outcomes. That fate determines where we are in life and nothing that we do would make it different. Thinking that way lifts the responsibility of our life decisions. There is no reason to regret what our lives are like or the decisions that we have made in the past because it was always going to happen and meant to be that way.
When we think that our lives' are products of fate and destiny each decision matters a lot and should be taken seriously. This life is harder to take in. It means that all the responsibility lies with us and there is no way out of it. Although, I would still say that regrets are unnecessary. You cannot change the past or what you have done in it, so what is the point in dwelling on it with thoughts of regret?

Meanwhile, I sit here. Wondering, wishing life were easy, and grateful that it is not.
