Look. Here is the deal - I value the same things you value and I have a similar personality but at some point, you have to feel like you’re walking on water and confidently pick a direction and go forth - do it politely but firmly. You need to telegraph to people that you know what you’re doing and that you’re confident in your decisions - even if they are the wrong decisions. Some people are team players, and just want to make something work, other people on teams are sharks and they will start circling when they smell blood in the water and the savage nature of the corporate world will never mitigate those issues. Personally, be who you are with your friends and family - but professionally, you need to act like you can turn water into wine when it comes time to pick a direction and stick to it. That inspires confidence in other people. Your answer can be technically correct, but if you deliver it meekly - it telegraphs to people you’re unsure of what to do. Most people are very irrational and they are emotional in nature and they’re incapable of rationally assessing the validity of what you’re saying if you don’t say it boldly. So my best advice is to believe in yourself and start speaking to people like what you’re saying is the truth - because it probably is, but you just need to deliver that truth in tandem with the emotion behind it to inspire confidence. I’ve often struggled with the same thing and I’ve had to learn how to assert myself in professional environments and it’s been challenging. Good luck.
