Hey equinox_code,
The first step is always the most important step. You know something is not right in your life and now you are planning to do something about it. Thats great!
And the rest is really really simple.
You can be whatever you want, but you will only become what you do. Figure out what you truly want and then figure out how to get there. And then the most difficult thing, do it. One step at the time. Stop living in the fear that you may not make it, live with the knowledge that whatever happens you will be able to handle it. It is vitally important that you stop making excuses and take responsibility for your life. If you let your fears keep you away from your dreams you will never be truly happy. Without risk, there is no reward.
But please be realistic, dont expect to get a high-paid job directly after graduation.
