you're right, things do change. @Snowie and sometimes that means what worked last time might need to be tweaked this time, or maybe we need a whole new strategy. i guess the whole 'what worked last time' can be a lil annoying to hear sometimes but perhaps it's also a good reminder that you did get through it last time. 

it's interesting what you mentioned about seeing no improvements - i think you've probably heard this many times before but it is true: progress isn't always linear. i feel like this picture explains it well: 

the improvements are there, maybe its small or maybe you didn't even notice some of the changes you've made. but regardless, it's exists. when you're currently going through a challenge, it's sometimes hard to see all the progress and results... but when you overcome it, it's easier to look back and see the progress. maybe right now you're still in the middle of it?
