1) You will most likely live to be over 125 years old:
If you are in high school or college right now, medical technology will progress enough in your lifetime that you can expect to live past 125 years of age.
This means you might want to take a few hours now to plan your career. What's a few hours and a few dollars when you have another 100 years to spend?
2) Without a plan, you are like a ship without a rudder:
Without a career plan you will be blown off course by the slightest breeze.
College students are well known for changing majors, losing credits, dropping out, or taking too long to graduate.
Without a clear career direction, or at least a few selected career options in place, they wander from major to major. When times get tough, and the classes become hard, self doubt begins to creep in.
Having a firm career direction will help keep you on track during tough times.
3) You will have more than one career in your lifetime:
In the United States and the rest of the developed world, it is becoming common for a person to have more than one career in a lifetime.
Doctors and attorneys tend to stay in the same field of work, but engineers, computer scientists, actors and entrepreneurs may change the type of work they do as many as five times or more.
4) When in doubt aim high:
If you are torn between becoming a doctor or an engineer, aim for the highest paid career that also has the most demanding educational requirements.
If you try the hardest first, and decide it's too tough, or you just don't like it, at least you will have tried it. It's easy to move to a field with lower educational requirements. It's almost impossible to move up once you've started.
5) Do what you like and the money will follow:
If you work at something you like, you will be good at it, and the best people usually rise to the top. However, don't do something just for the money unless you do not have any better options.
It's almost impossible to be successful doing work you do not enjoy. Actually you can do it, but you will hate it and life won't be much fun.So pick the right career now. You will be glad you did.
