A lot of developers I work with struggle with self-esteem. They do not see themselves worthy of success. When you would you like to get to senior? Would you like to make more money? Would you like to move towards you know a better salary? themselves don't even believe, they don't see themselves worthy. And this can come from different factors, we've been told no, we've been rejected since we were kids.
And what happens with time is we interiorize this negative feedback and they become self-limiting beliefs where we don't see ourselves as worthy. And if you really want to get to the next level, the first thing is to believe in yourself that you can get to that next level. It's having that inner belief because this will fuel you. In our job, the challenges are many. Okay, you will get bad feedback, you interviews will go sideways, you'll have projects that don't go forward and you need as much self belief as you can have.
