My son is only 12 YO and up to this point has been pretty low maintenance, but I live in fear of the teen years ahead.
I recently told a new mom that the thing I had learned the most from parenthood was deferred gratification, so anything he does that really seems to grate on my nerves, I am able to say, someday this will end.
I guess what makes it easiest for me is that I can see he is a combo of both of us, so when he acts like his dad, I remember the other half that is like me. The other day my husband said, He may have gotten being smart from me ( I let him think this, ha) but he got being a smart ass from you!
