Please help to provide me with some career advice:
In my previous summer intern experience, I did quite well in the projects compared to other interns. However, my boss told me that they were all "surprised" to see that my final presentation result was far better than other interns. Also, some managers' feedback was that I sometimes seem "careless" or "dazed".
After self-reflection, I realized that I'm the kind of person who is very easy going and work with colleagues in a relaxed way. Some colleagues also mentioned I am "too naive" and should be more "seasoned". Also, I feel that I am sometimes too humble and don't carry enough confidence. For example, for things I don't know well enough, I will be 100% transparent, while some interns will pretend that they are a master in this topic even though they aren't. However, during the project presentation stage, I would be sharp, confident, and communicative after enough practice and preparation to boost my confidence".
Could you please share some advice on this issue? I'm thinking of how to boost my confidence and find some methods to look "sharp and smart" even during daily routines. Also, instead of being "naive and humble", I would like to project a professional image of being "seasoned, sharp, and professional. Thanks a lot for your insights.
