AVOIDING FATE

I don’t know why but I believe in Fate.
What is Fate? Can we change our Fate?
Many Times I say or I hear: It’s their Fate? But is it?
I’m not a philosopher, but Fate is something we can’t control (or may be you can, who knows?)
When we think that something will have high probability of happening and we take measures in order to avoid that it happens, which of them is Fate?
Was it Fate to avoid the problem?
It’s very complicate!
I’m going to speak about myself. In general I don’t believe in anything that I can’t control as is religion. Things happen because they have to happen!
But I believe in Fate! I can’t control Fate but I need to believe in something I can’t control, and
this is Fate!
