Do you beleive in coincidence?

How many people come to our life in order to change it? How many times we don't even recognize the influence we get from some person? Do we have time in this kind of system to even take attention on it?
In my opinion, there is no coincidence. My birthday is soon, 27 years old, not a lot to have experience like some of you guys have, but enough to realise that life brings a lot of situations in which we have to find ourselfs. Even someone you meet on the street give you some kind of influence. The impact of influence can hit and awake different feelings in our body.
Let me tell you a small story..

After my bachelor degree, I had been in the situation to find a job as soon as possible. The circumstances in my life had been difficult, so beside sending my CV to many address, I tried to do my best to use the contacts I had. The path took me to the man I know from stories, as someone who is working for a company in wastewater treatments field. I had been very happy I got a chance to introduce myself as a young ambitious person ready to work. I had been 23 years old then. The result of this story is that I got so disappointed in life, cause his only goal was to use me. In the moment of our conversation, I realized his intentions, I got up from the chair, gave him a hand, and said: "Thank you "Mr Coincidence"!".
I had been very angry in the begining, but I told myself: "Let's see what this coincidence brings."
This kind of life situation gave me a lot of strength to continue my studying, gave me faith to beleive in myself much more than before, gave me motivation to success, because I never wanted to be in a position that someone try to manipulate me or try to use me again, just becouse I'm in the hard position in life.
Today, this "Mr Coincidence" and I working for the same Institution. Can you imagine his face when he realized that in this moment we have changed our positions? Becouse today I'm the one who is up. The only words I have for him is: "Thank you!"
He made me a better person than I was.
I would love to hear some of your coincidence and ways you are thinikg about influences in your life?

My favourite coincidences are the small one which involves lovely feelings.. like this one ..
