Did I developed a bad habit?

Currently I'm only playing coop mode, and I'm only playing nova, zagara, tychus and dehaka who has supplies start and not paying attention to supplies anymore, then after when I playing anyone who doesn't have it and needs supplies I feeling annoyed build supplies and thinking the entire time, man those 100 crystal and time is such a waste to build. Wanted ask did I developed a bad habit not wanting paying attention to supplies?
