Getting a good job, working long hours, keeping your skills up to date, managing the politics of a company, and establishing a work-life balance are all extremely difficult tasks to do.

Respecting institutions, having good manners, and displaying a sense of humility, on the other hand, are all [relatively] simple things to do.

Get the simple things right first.

Successfulness will not be achieved alone through these methods [respect, good manners and humility]. However, if you do not have them, you will be held back and will not be able to reach your full potential.
