My main inspiration is music and people. Music creates mood, and people energize. I'm talking about those people who burn, not smolder. People who create something and strive for something.
In my opinion, the key to development is to surround yourself with the most inspiring and talented people. It's like in sports, you need to practise with strong players to develop yourself and to achieve success.
About motivation, it is simple - my parents. Being ordinary working-class people, they still gave me everything in this life. I never needed anything more. I'm 33, and they still go through all my ups and downs with me. They don't understand anything about IT, but I still share our news from Aeroji with them. Now, I have kids myself and I hope to be the same role model for them as my parents are for me. Do what you can do the best way and enjoy the results.
