Although it is good to offer your best to your service and be friendly with all at your workplace, there are certain aspects you better follow in terms your relation with your co-workers, and superiors. You may get tempted to do something to impress your supervisor or boss and you may end in disaster on account of your lack of skill on that very matter. This may lead to a great acrimony inflicted upon you due to your failure seen as irresponsibility on your part.
Usually you will be offered some remuneration for your initiative to jump for the job beyond your arena. If your effort goes right everything will be fine. But if it does not you are surely in soup. The initial question will arise as to penalize you for your unprofessional approach. Suppose, you are a clerk, but previously you had interest on car repairing which you did not pursue subsequently as your career, and which is not your forte, and on a fine day you initiate yourself to go for repairing the car of your boss who faces some car problem, there is a fare chance that you are pushing yourself to the impending danger. Since, you are not having a practiced hand in car repairing the fair chance is to get your initiative ended in a blunder. And for your attempt you can expect to meet a series of unpleasant circumstances in your office.
It is always best, therefore, to remove yourself from the affairs that do not belong to you. Too much doing can result in massive undoing. So, you need to take a very practical stance in your professional approach. Your stand as overtly faithful to your superiors may not be seen in a positive way. Therefore, you should be very practical in your professional attitude and act within you sphere.
