Yay! Wonderful post, everyone should do one of these, to remind themselves why they are so loveable!
Remember, change is not always a bad thing, it's just forced change. If you always leave the shower on hot when living by yourself and your new partner wants it on lukewarm, then it's kind (and safer) to always leave it at the lukewarm temperature for them when you finish. It's something you have to change, but doesn't cause you any problems and in fact makes you more considerate (i.e. if you live with many people, this is the only really safe (scalding hot is not safe) and friendly way to keep things, I have found).
Grow, learn and change, just make sure it's the right changes and you consider them an asset or improvement to who you are.
All the best,
