The best way to be a good dev is to be a bad dev. Once I realized this it was easier for me to make mistakes & learn from them quickly. As a dev the one thing you should get comfortable saying is "I don't know how to do this right now, but I know the steps I can take to find out" https://twitter.com/codeFreedomRitr/status/1332349446957494272
One if the best ways to be a better dev is to ask ALOT of questions. Don't feel bad about asking questions either! For the first 3 month (honestly the first 6 months) you should focus on asking as many questions as possible so you can understand the workflows and company goals
I have a lot of feedback and suggestions about this but I can't write everything out right now, but if you want I'm down to jump on a zoom call to ask any questions whenever
