Our acting friend, Colleen, will tell you that the third common way that talent mistakenly get in their own way is by not being able to listen. Most talent can hear, but being able to take what we hear and then actively listen is a different matter. She refers to this as "Special Snowflake Syndrome," and it comes down to being able to acknowledge an idea, think critically about it, and then take action on the idea (or parts of the idea) that will help you move forward in your career. In her words . . .
I am about as stubborn as they come. And there's a place for all kinds of stubbornness, from grim determinism to relentless optimism—it takes grit and a certain willingness to overlook the overwhelming odds against success in this crazy business of show.
But failing to observe protocol or established rules of etiquette is dumb. At best, it makes you look foolish; at worst, it angers people. People have lo-o-ong memories when they've been angered.
Sometimes, doing the wrong thing happens out of ignorance (which is another good reason not to move too fast). If you know you're doing the wrong thing and decide to do it anyway—which is totally your prerogative—don't be surprised if you end up paying a price.
No one who supports your career wants you to "pay any price;" least of all yourself! We all go to great lengths as humans to avoid pain or negative repercussions. Your career is no different.
Made a mistake due to being naive? Address the issue directly with the person who was harmed or affected by your malevolence and ask directly how you can make it right. Then be willing to go the extra mile to repair the damage and acknowledge that it isn't going to be a quick fix. Feelings take time and continued effort to be repaired when a relationship has been hurt. Be willing to take action for as long as it takes to show your changed ways.
If harm was done by choice, it may be a different scenario and the harmed individual or company may be less receptive to your well intended efforts. In this case, the best you can do is commit to make it right should the opportunity arise and change your ways before enemies become common. There are talent whose name is mentioned along with an eye roll or deep sigh merely because everyone in the industry around them knows what kind of person they are to work with. Will they not get work? Not necessarily. They may still be hired, but only as a last resort and no one will go out of their way to make their day on set any more positive than they absolutely must, which continues the bad wrap.
Advice isn't always warranted. It isn't always easy to hear. And it doesn't always give us confidence and motivation. What advice DOES, however, is give you room to grow and build a career. Heed it only from industry professionals and don't miss the opportunity to take action and show commitment to your professionalism and craft!
