I build a framework single-handedly to make my work at a customer project easier. It is good and thought out but now more and more people join the fray, suggesting and wanting to change it in a way I didn't envision it. Therefore I am arguing and discussing with them their points but it might look like me being defensive and immature where I just honestly disagree with them. Fuck my life.

Well, only if their points are invalid. I too have such situations at work in which I introduced several new ways of handling our php projects and the lead developer did not like it(he is a procedural style past it in the html ninja) and eventually my manager ruled in my favor.

If your points are logical then that is that. If only you agree with your points and several others disagree then its time to pull the good ole internet resource on best practices and slap them hard with it!

@Brosyl I don't own it, the customer does. I'm just the original author and main maintainer and user. It is just hard because I'm also younger.
