Good read and I'm at this very place with my mindset abiut being brave with your decisions. Choosing comfort is easy but breaking into the unknown is scary. But whats inherent to growth is change and changes comes with uncertainty. I tendered in my resignation only 3 weeks ago and this week is my last week with a company I've been with as a Software Engineer for the last 7 years. I'm no longer learning new stuff. Yes the pay is good but I'm unstimulated like how I once was. I'm mentally fatigued each day not because of work pressure but the mundane nature of everyday work. I'm afraid but change looks like the only way out.
Looking forward to the best for myself. Fingers crossed
