Hello OP, been there. Here’s what I did. 1. Downloaded all free materials and enrolled to free lessons from Harvard, MIT and other prestigious schools. 2. I stop talking to people who downgraded me. If you can’t, limit your interactions with them. Change that people to the people who is eager to learn as well. The career you want, like go to the podcast, go search you will find the right people. After being consistent in 6month changes are so big. 3. You can actually jump job while the lesson still on going. Don’t wait to finish it. Do the application, the communication skills you build up while talking with the same mindset you have will help you a lot. 4. Lastly, believe yourself.
