Of course there can be reasons from outside. I found that usually it is better to concentrate on the things we can influence, because we can't really change things that are outside of our control.

I guess the best approach is:

1️⃣ Try if you can change something

2️⃣ Try to change the environment

But it is important to know, that if I am the problem, changing environment won't help, and vica versa.

Pura Vida! 💜
