Honestly I've been pretty sloppy and disorganized about it, so I don't have much sage advice. The one thing I had going for me was consistency, so I guess there's that. Having one of those pull up bars you out in a dorrway helped, since it's always right there. If you've got an actual routine you can keep to, you're already in a faster lane than me.

Diet is very important too. I noticed when I started eating more eggs and less beer there was a noticeable difference in a couple weeks.
