Thinking of what we want, depends on our Thoughts. Whatever our mind can conceive, it can achieve. As simple as that.
Thinking pattern is the main thing - we shouldn't restrict our mind, saying that 'no, that's not gonna happen, I can't do this, I can't get that'
The answer is, You can do anything - provided you have a vision, determination, and persistence for it.
Sometimes our thoughts are that small in front of our capabilities, as me (in this picture) looking in front of this huge Petronas towers.
Therefore, think big, get up, work for it, and get it done in your way.
Best of Luck !
