Think about it.
When you embark on decorating your house, you strip the walls of their paper and whether you’re going to paper it again or just paint it, you’re going to uncover a lot of mess.
It has to be patched up, made good and even. You wonder why on earth someone would behave so shoddily and irresponsibly. You think, why should I be sorting out someone else’s fuckups? Why do I have to make this better?
Well, it’s the difference between a passive child or a responsible adult. You have the opportunity to make things better AND you can decide how to build up the new surroundings. You can make yourself dedicated and capable of doing a good job and it makes other people’s behaviour irrelevant.
Make yourself a beautiful mansion, leave the ruins to others.
