Being a developer is hard, and taking the first steps is even harder. You have to constantly practice, master large amounts of complex information, you will definitely face unexpected challenges that can easily scare away even the most interested and motivated specialist." You will have to hear a lot of criticism, and I will make a reservation right away: correct criticism is what helps to become better, does not hurt self-esteem and contributes to professional growth. It is very important to distinguish criticism from criticism. Notice when you are used to reinforce your unhealthy ego or assert yourself at your expense. Such situations are unlikely to be frequent, but you need to be prepared for them too."
