A variety of work skills is assumed to be a good thing.
This is true when in the work world and selling yourself to a prospective employer.
Do not suffer from this assumption because some skills in fact are detriments to your professional career.
Being able to do more than one thing at a time seems great but multitasking can be seen otherwise.
It shows that you may not be able to hone in on one project or task in order to complete it in an efficient manner.
Do what you can to learn to focus.
You may be a hard worker but you also need to be an efficient and effective one.
Being considered to have a work ethic is good unless it means you work a lot of hours and do not accomplish much.
Work on your time management skills if this is the case.
The assumption that being an over time worker is a good thing is wrong.
It can be seen as an ineffective use of time and lead to burn out.
Work hard when you need to and ease off and step away as needed.
A can-do attitude is seen as rather juvenile in the work world.
Realism is appreciated by bosses.
It is a detriment to the company if you promise something on too quick of a time frame and then do not get it done.
There are others relying on the date given that you had no real chance to make.
Learn to make a better assessment of the length of tasks.
Honesty is better.
Do not be a braggart.
There are subtler ways for your boss to know your value to the company.
Bragging only leads to jealousy and resentment by others.
Just because a skill sounds good does not mean that it always is one in the real world of work.
