Get into the HABIT of finishing what you've started. Throughout your life, that alone will make you more valuable than the next guy/gal. NEVER give up.
NEVER assume you will be GIVEN ANYthing, ALWAYS assume YOU will pay for it willingly.
Quitters and slackers get NOWHERE and can NEVER negotiate effectively for better pay.(Unless you choose to be in a union of some kind.......)
By developing a broad based knowledge bank, you WILL be more valuable than the next guy/gal and therefore CAN negotiate better pay.
No matter WHAT job or position you have at any given time, ALWAYS dress, act, and perform like a PROFESSIONAL. Remember; HABIT.
Good luck and good hunting....
