Doubting your custom story.

[The chaser]

Modding must be a pleasure, not an obligation. So, if you ever get bored and you fel like quitting, think in doing something different: Learning how to implement something custom, think in cool ideas, etc.
Something that can feed your mind in this aspect is to play other custom stories: I'll tell a story:

I was one day, tired of making my CS. I said: hell, I want to play something. I went to Moddb, got some custom stories, and they were really bad: Although this may seem a thought of an as**ole, I thought: If every story is so bad, mine will be reminded.

Try it, it works. At last for me.
