“let it go” is truly one of the most beneficial phrases I ever learned. I understand exactly where you are coming from, I have been there. a true resolution is always out there. don’t loose hope. while I do not know specifically what your situation is, let me tell you a few things that helped me with mine. most importantly- you can not change other people, you can only change yourself and your perspective. this is a huge one. try to understand that the people around you (all people around you!) want exactly the same thing you do…happiness. some are unproductive, some fearful (a lot are fearful!), some resentful or angry. you can only control what goes on in your head and you have no idea what is going on in theirs. so be kind and do not let their behaviors make you resentful. that resentment builds up- here is where you let it go. do not take it personal. look at any undesired or “negative” situation as a chance to learn. this turns it into something positive- and there is ALWAYS a positive.
I was so miserable at a job that I was truly good at, that for the last 2 years there I had migraines everyday. I would go for coffee with my friends sometimes on the weekends and see the woman working there and think that I could be happy doing that. I would joke at work and say that I was just going to quit and buy a coffee shop! well, one day I had an appointment somewhere I had never been and decided to take a walk and check things out. what I found was a tiny little coffee shop with a piece of notebook paper on the door that read ” closed due to unforeseen circumstances, business for sale”. I called. they were desperate. they had an injury and could not afford to keep it without it being open. I had enough equity in my home (the one I was able to buy because of the miserable job) that I was able to buy the shop. I have been there over seven years now and I am happy. I am telling you my story because I want you to truly believe that no matter what, the universe will take care of you. it will always give you what you need. sometimes what you need is a lesson. I learned so much at my job about myself, others, technical things. a lot of these things I did not even realize until after the fact. have faith. nothing is without a reason. smile and know that your happiness is there. change your perspective and ALL else will fall into place. I wish you joy 🙂

Tricky one indeed!
Like you, I have a formula for such situations and people:
1. Accept the situation/decision/action
2. Attempt to change the “perpetrator”
3. Walk away..

As you say, your lease probably dictates that 3. isn’t an option…unless you’re really strong, and willing to take a financial hit.
Sounds like you have tried 2…..and failed
So, looks like you are stuck with option 1.

However, to ease the pain a bit, you could:
1. Try to understand where the landlord is coming from…even if you don’t agree with him
2. Perhaps try and change your perspective or beliefs…seeing you have to live with it anyway. May as well go with the flow as fight it all the way…the only person who looses, that way, is you.

No easy answer, I’m afraid.

Unfortunately, the reality is…as long as you believe you have been hard done by and aggrieved…you will be bothered by it.
So, the only way to change that “bothered” emotion is to change what you believe about the situation. That’s just logic and maths.
Having said that, I know it’s easier said than done. We can’t just turn the tap off.
The trick is to do it in steps. We’re not machines. Is there a different way you could look at the situation?
For example….” I know x has happened to me. I would prefer that it didn’t, however, the realities of life dictate that these disagreements do happen to some people. It just so happens that it’s my turn to cop it.”
Now you are saying that it’s not AWFUL or HORRIBLE that it’s happened to me. You’re accepting reality.
Once you get to that stage…I would be looking at all the lessons you gained from having this episode. Are you a bit wiser? Have you had to stretch your thinking paths? Have you learnt any new life coping techniques? Would you approach a tenancy arrangement differently next time?
Now, just imagine that absolutely nothing bothered you. You would be always happy and never upset. That’s the goal we should be aiming for. Yes, you may laugh, no one will ever reach that place…but the closer we get…the less tiresome the world becomes.
