My motivation is that I grew up dirt poor as both of my parents dropped out of college to get married and then divorced each other like 6 years later. I grew up one of three kids of a single parent who had an ok job, but we surely struggled. Both of my parents have ok jobs, but I can tell neither of them are really doing something that makes them happy and rather just doing something they can live with to pay the bills. Despite growing up dirt poor I have had a lot of people do really great things for me in my life, such as helping us buy food and pay our bills after my parents got divorced, my mom didn't have a job, and we had no money. Additionaly I am greatful to my aunt and uncle for helping me pay for college and to my other aunt and uncle for giving me a car so I could get a job and get to and from college. It sucked sometimes, but I have learned to live with little and the experience has given my a big heart, compassion, and sense of need to return the favor to those who have spent so much time, effort, and money in me (which includes society...we were on welfare for years)
My motivation is that I never want my future family to have to struggle the way my family did. Additionally, I don't want a job were I feel liking I'm doing it just to survive and make due. I want to enjoy and be passionate about what I do. Money only has negative meaning to me, so I think it's nice dentists usually make good money, but really all I need is enough to take care of my family and not struggle doing so, and what is left over I believe should go back to helping others who were once in my family's situation.
It is hard to stay motivated, but if you really want something in life, I really think eventually you will get it if you try hard enough and don't give up.
Pre-dentalguy...you bring up a great point though. We all need a support network to help us stay motivated and focused. Most of us, especially myself, are at a very strange frustrating time in our life in which we are trying to figure out who we are, what we want out of life, and how to get it. It is a tough game. I've never been so confused in my life! The idea of even entering the real world outside the security of home and/or school is scarrier than hell for some of us. The only comfort I have found though is by asking others in my situation and others who have made it through my situation for advice and then slowly try to get things figured out. It is an important time to have good family and friends! You just got to stick through it and keep your eye on the prize. Everything will fall into place eventually, but not if you give up.
