Few victories on myself

In this thread I would like to share few victories on myself.
For me that's mean something because I have not believe that will work and perhaps yes.

My first victory is to have stopped drinking cola soda; in my past it was my "water".
I had never believed it, but when I have tried the substitution by another beverage, that worked. Now it's since 3 years that I have stopped.

My second victory is to have overcomed the love obsessional. I had a fake vision of love in my past: I wanted a relationship with a girl who didn't want it.
In my mind I couldn't accepted it, it was failure, I'm felt very sick and she couldn't to get out of my head.
I needed to work inside during 9 years but that's worked.
It's here where the quote of Thomas Edison had a big effect on me "I haven't fail, I just found 10,000 solutions that's not worked".

My third and last victory is to have overcomed my understanding handicap in my childhood: In the primary school I had not my place for this reason, so I am sent at the handicap school where I was been during 9 years. And I have not only overcomed my handicap. I have learned to ride a bike and a horse, to swim, to skate, to cook, to tinker, to peint and to travel.

Many things are possible if you really want realize something.
In these victories, do you know what is the main ingredient?
The big "WHY".
