If you have made far enough to ask, you are a developer!
Here are a few things I try to tell myself on a regular basis.
There will always be people who know more about language_a or framework_b than you. You can learn from these people so don't let them make you feel like a fool.
There will always be moments of self-doubt. These moments are great for taking a break and asking a colleague to review your code. Some positive feedback or constructive criticism will distract you and get you coding again.
Use git. Commit often. push daily.
If you don't know, google; then ask.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
