Everybody you meet has got opinions. People think what you do isn’t good enough whether it is writing, cooking, gardening, playing sports or anything else. There’s someone always out there who wants to give you there opinion and tell you what you did was wrong or isn’t good enough. They might not be good at it or know much about what you’re doing, but they somehow know a way, which will help you become good at it.
They might tell you that this works better because it sounds better or because someone else is doing it and they are good at it or it feels better or they just know. Sometimes it could also be someone who hired you as you were the expert, but once they see your ideas and the way you want things to be handled. They have a cross in opinion, because they feel that their way is right because that’s what they want it to be done, even though you’re the expert.
When someone gives you an opinion you have two choices, you can either ignore it completely, ignore bits of it and consider the good parts or take the entire opinion into consideration.
You need to remember, it’s just an opinion, the person who has given it to you might be more experienced, more knowledgeable, better than what you are, but it doesn’t mean that their opinion is better. An opinion is just an opinion. At the end of the day it’s all about your idea and your work (and it is probably better without those opinions), you can take a note of the opinion and follow it only if you want to.
