• Question yourself. Ask more questions smartly, professionally and simply. Ask yourself first.
• Search by yourself. Search on Intelnet, in libraries and books. Find the best existing solution to your question. Sometimes, maybe asking for a professor directly is the best solution, especially when you are in an urgent situation. If there is no one proper solution, work out one all by yourself. And sometimes, a few researches are needed.
• Solve by yourself. Just do it when you finally get a solution. When you meet new troubles, go to step one.

The best way is to be prepared before the bad things occurs. Asking questions, searching and researching beforehand are never worthless.
Never give up untill the last second.
