(a). EXCEL ACADEMICALLY: I always advice people to pursue a further education even after a four year course or per time course,not only get serious and earn good grades,it is good to pursue more ,for example even after a four year course in civil engineering ,getting a masters degree would do you no harm so why not go for it.
(b). LOOK FOR THE RIGHT PROFESSION: After school it is very wise to look for an environment that favors your profession ,go online,carry out surveys on salaries,monthly and annually before applying for a job,very important you know what you going into.
(c). HAVE A POSITIVE ATTITUDE: Not really much to say here than never give up,always have a fighting and optimistic attitude.
(d). WORK YOUR WAY UP: When applying for jobs,it is wise to apply in many other places at once ,do not limit you options,look for level entry jobs and work your way up to the top.
(e). CHANGE IS GOOD: After sometime in your job,it is always good and advisable to change environment,always search for a better paying job than your present jobs,do not wait till you are sacked or till you have had a problem at your present jobs before you move on.
