I got my first real job after months of proving myself during my internship experience. But after getting into the working world, I struggling immensely with settling in. I was clueless about some critical things, and while I was willing to learn, sometimes I thought I would never get it! I felt out of place and like the "newbie" which I was, I used my limited experience as an excuse to complain a lot. I'd ask my supervisor for more time to get things done because I wasn't familiar, or I expected him to be more understanding when he got mediocre work because I was the newbie.
Let me tell you now, if you are where I was when I started out in my career - get rid of that nonsense. Always finding excuses and expecting others to understand just because you are "new" or "inexperienced" is a sure way of killing your career.
I recall at one point, I was tasked with a project and at that moment, because I just wasn't getting it 'right' - I reminded my coworker that I was a newbie, so he could have been more understanding. Thinking about it now, I sounded so silly. I would often ring out that word because I felt my coworkers and supervisor should understand, but at the same time after 3 or 6 months in, sometimes no one really care if you are a newbie, you just have to get the work done, it's that simple.Being inexperienced doesn't mean it's your ticket to excuses of not putting out your best or getting things done! So what if you are new or inexperienced, use it to your advantage to ask all the right questions you need to know.
Think about it, when external clients or stakeholders make a request to get something done, the newbie line won't work. How the heck would you look saying, "I am sorry I cannot do it because I am new and inexperienced?"
So here's what I am saying, get out of the newbie mentality and get rid of all the excuses. If they hired you fresh from college, they hired you for a reason. Or better, if they hired you, they hired you because they believe you have something of value to offer. So instead of complaining about being a newbie who needs more time or understanding, dedicate your time to getting familiar with the areas you are not most comfortable.
Once you have committed yourself to getting into the groove of things, you will feel more comfortable and confident and will start realizing how soon that newbie, inexperienced mentality leaves you.
