They are adopting Hannibal’s motto: “I will either find a way, or make a way.” You must do the same. The trick is to want something badly enough that nothing will stop you or dull your energy. Fill yourself with the requisite desire to reach a goal. Train yourself to not give up as easily as you did in the past. Keep attacking from new angles, in new ways. Drop the background doubts and continue striking with full force, knowing that you can break through anything if you don’t let up. Once you sense the power in this form of attack, you will keep returning to it. "
