How can my paragraph be edited?

First off, the semi colon before do is not correctly placed and the sentence sounds sloppy. Rather say....Does earning one million dollars, climbing Mt. Everest, and becoming the greatest ping pong champion of all time sound like far-fetched achievments?....that sounds better. Also, do not put a hyphen between one million. Secondly, the i think not phrase sounds corny. Take it out. The next sentence is great except you need to remove the double -, you only need one. Lastly, the last sentence should read... and using the good education I have received...in order to have the verb use agree with the other two ing verb endings.
