"If you wanna make the world a better place/Take a look at yourself and then make a change". Micheal Jackson. I think that to make positive improvements in your self first you must make goals based on who you want to be and what you want to accomplish.Then make plans to reach the goals and act on them.But I believe you need to know yourself before you can know who you want to be.These are some links to tests that will tell you things about yourself you might not already know.
