The biggest challenge in my work experience I have faced, and I'm sure I'll be facing in the future also, is communication. People have problem how to talk with each other, people have problem even how to give direction, people about the world, people have problem how to help each other because that's something that we don't take seriously often. So almost all the time when I feel that there is something going on, I feel that there is a tension between me or another team member, I am always the first person to ask for a meeting with them, or call, or in person, and I try to be very direct and very honest, and I ask, I feel something is going on, I would like your feedback, or I want to know what's going on, like there is something I'm not doing right. And the outcome usually depends on the other person. Usually the process of communication goes very nice, but the outcome depends on the other person. Sometimes the outcome is really nice, sometimes the person does not really want to talk, or not convinced the way I try to explain things. But usually the outcome is better than the first situation. So this is how I resolve problems. And then when I see that they want to include someone else, a third party, I'm happy to do that. Just ask another person what that person thinks about this thing. So that's the thing, that's the challenge, I could say that I have been facing in my life, but that's also not the biggest challenge, because I don't think...
