I'm an optimist and I don't often feel disappointed because I can find some good in everything
This is me. And also because I'm so optimistic about things I move forward with, I usually get them. I went for a huge promotion at work, spent weeks preparing a presentation, researching, liaising with colleagues about different aspects, learning all I could.
I recall thinking the night before my interview that it didn't matter if I didn't get it. I knew that I had given every ounce of enthusiasm and effort and I knew I'd tried my best. If my best wasn't good enough then the person that they would choose would be the right fit and I could sit back knowing the project and promotion was in the right hands and that was enough for me.
I did get it though and I knew I bloody deserved it. Optimism helped, but it's not just blind optimism, it's having a belief in oneself I think.
I believe in myself completely, totally and 100%. If I want to do something or get something and I have that feeling in my gut, I'm going to go and do it or get it come hell or highwater, and that's where my optimism comes from. Knowing that I can do it, or get it because I'm so confident that it will affect my life positively.
It's hard to explain, but that's how optimism manifests in me.
