Hehe, you sound like Emporer Palpatine, giving Anakin advice. Anakin would have faired better with the Jedi, and stick to the code. With the Jedi, It's all about earning respect. As Yoda said in Empire A Jedi must have the deepest commitment, the most serious mind, So why worry about what one thinks he can or cannot do. That was lukes problem early on. You do what your master tells you to do. That was Anakins problem. When you show defiance, you loose your trust with your master and peers, no matter how good you think may or may not be.

Lukes situation was different than that of Anakins. He didn't have the Emporer hanging around. True, that Luke lost many loved ones, but he was able to embrace that loss to make him stronger mentally. In the end Luke had 2 specific goals, and that was to become a Jedi, and bring his father back.


And of course this is just my own opinion.
