Don't cry over spilled milk and a client lost!

Just lost a client. It's not the end of the world. It's definitely not my first time. Yet, I can't help myself thinking about it. It still hurts a bit. Rest assured that I didn't come here looking for a shoulder to cry on. I would like to be prepared, let's say much better, the next time it happens. How? Well, one of my colleagues recommended this place. Said I should expect much, but it can be a useful thing to do. Now, I believe that an attitude is everything.

My colleague said that I should cry over spilled milk and a client I just lost. I was about to say, it's easy for you to play smart, but then I remembered that he had a similar situation or two. I'm not saying that you should turn your situation into a drama. If a client has made his decision about leaving then I don't have the slightest intention of begging him to stay with new better prices or similar. It is what it is. On the other hand, I want to come up with a healthier attitude when this situation repeats itself the next time. How?

Should I say something like I read somewhere, the Internet is an endless ocean where everyone can catch a goldfish to grant him more than one wish at any time. Well, this is an optimistic view, actually too optimistic. You know how it goes. You build your relationship with a client. You invest not only your time, but your emotions, as well. Now, if you are going to say to me that the best way to forget about your old love is to fall in love again with a new person as soon as possible, then I'm going to be disappointed a lot.

Every new client I find puts a smile on my face. Every client I lose makes me wonder what did I do wrong. Maybe everything is OK on my end. I'm not losing my clients as if it's an epidemic. Or, I should have some thicker skin for a change, that's all. For what is worth, I already feel better after sharing my situation on this forum. Let's see if I'm going to feel even better when I hear some thoughts from people who went through similar situations.
