How do you motivate yourself to learn new characters?

For some time now I've been thinking about tipping my toe into a second character next to Baiken.

But I feel like there is still soooo much to learn for Baiken, that taking on another character would be like breaking off my Baiken training.

On the other hand I feel like I put so much work into Baiken already (about 100 hours). Working my way up to that point with another character feels like a daunting task.

I also only have 1-2 hours every couple of days to play and I'm not sure I can deal with learning a new char and maintaining my Baiken skill level.

Hoe do you fellas deal with the urge to play a new char, while trying to not lose focus on your main?
