I can't stop to underestimate myself on my programming level so that I'm not applying to some cool jobs because I think that I wouldn't make it, while knowing in my deep mind that I could totally do it.

I've created and sold websites for companies of my city and cities around mainly when I was ~16yo and even from time to time until now. I've made and sold multiple mobile apps, some that have currently thousands of clients by subscription. And I have always since 13yo at least a project in my hands.
