It's an **achievement**, so I might feel that I **achieved something** or that I have a **sense of achievement**.

*Achievement*:

> something accomplished, as through great effort, skill, perseverance, or courage. ([Random House](http://www.thefreedictionary.com/achievement))

*Achieve*:

> *We have achieved what we set out to do.* ([MacMillan](https://www.macmillandictionary.com/us/dictionary/american/achieve))

*Sense of achievement*: 

> *It was hard work, but the sense of achievement is huge.* ([MacMillan](https://www.macmillandictionary.com/us/dictionary/american/achievement))

> *Even a small success gives you a sense of achievement* (= a feeling of pride). ([Oxford Learner's Dictionary](http://www.oxfordlearnersdictionaries.com/us/definition/english/achievement))

Note that this last example calls out the "feeling of pride" that is communicated by this phrase.
