I have seen a lot of people come and go at workplaces. Some stay, some leave because of another job offer, some get fired and some get laid off.
I think a lot of us shine when we start somewhere new or if we get promoted to a new position. But after a while we might get comfortable in what we do. Some might think why go the extra mile since somebody ells is getting all the attention? Sometimes it might be hard to stay positive. But you never know what the future holds for you in storage. My key to success is never, ever, get comfortable in what you are doing. Look for opportunities. Volunteer to help your colleagues. Suggest new ideas, remember no idea is a bad idea. Basically show your full potential at all times. Network with people. I know that if you do these things you can and will be successful in what you are doing.
Here's a quote from William Boetcker:
"Your success depend mainly upon what you think of yourself and whether you believe in yourself."
