If you want to succeed in any field you simply have to manage your time in such a way that you accomplish your goals in the shortest space of time possible.
There is no substitute for old-fashioned hard work but you can certainly take short-cuts along the way by increasing your work productivity – so you do more in less time.
You should also learn how to delegate tasks to others so that you can focus on the important things. It is virtually impossible to move up the ranks in any company without learning how to delegate effectively to the right people because this is the only way to maximize your output and value. It may be hard at first, particularly if you're a perfectionist that believes no one can do things as well as you can but there is no moving up without letting go of the small things. When delegating always ensure you're selecting the right person for the job because if the tasks set out is well above their abilities and pay-grade you’ll only cause irreversible damage to the person’s confidence and set your own goals back. If one person cannot handle an entire task be sure to split it up so that it can get done completely and on time.
It is also important to be open-minded and approachable so that people will see you as a friend rather than an enemy which is a big motivator for them to complete whatever it is you’ve requested of them. In addition always set specific guidelines, standards and deadlines so that nothing is left to chance but don’t micro-manage people – or risk their loyalty and effort.
“No man will make a great leader who wants to do it all himself, or to get all the credit for doing it.”–Andrew Carnegie
People that are the most likely to receive a promotion are also those who are the best team-players because every successful boss knows that the fate of their bottom line never rests solely on the shoulders of one man - even though some may come close.
Being a team-player means that you should always give credit where credit is due. If you're being praised for successfully completing a project make sure to mention those that without you wouldn’t have been able to cope and do this in the most pleasant manner. This doesn’t mean that you shouldn’t take credit for your own work – as this is the only way to ensure you're on the short-list for the next promotion but, this doesn’t mean you should take all of the credit.
