How do I express my thoughts effectively? I think one thing and say something completely different.

Sri Sri Ravi Shankar:

You have already asked this question effectively, that you want to express your thoughts.
Do more of advance courses. Don’t you see you have already improved?
How much have you improved? 50% you have improved? So you already know how you can improve another 50%. More advance courses.
Also repeat the basic courses. Don't think I have already done the basic course once, no!
If you repeat it, it brings you to a higher plane every time.
