Achievers attitude towards challenges!
What’s the attitude that the majority of successful people have when faced with a new challenge? They solve it! And if they don’t know how to solve it, they learn new skills and solve it!
For example i had to do a banner for a school project and my “Photoshop knowledge” was close to 0. Did i let that stop me or make a “cheap looking” banner in MS paint? No, it didn’t! I’ve used the most powerful tool: Google to learn (meaning to change your behavior and apply it in real life, not simply accumulating knowledge).
That’s what we could all do when faced with a challenge (or problem, like most like to say), develop your “skill to develop new skills” by modeling other people that are more advanced in that field, they’ve been there before so they see the fix to your problem almost instantly because they have a higher perspective on it. Pay a mentor if necessary, if not, at least use Google!
Albert Einstein said that you can’t solve a problem you’ve generated if you keep thinking the same as when you generated it, that’s why you have to advance to another level in life. Once you’ve advanced to a higher level in your life, problems that seemed impossible to fix will seem like a breeze now just like the man who swim in the arctic ocean isn’t afraid to swim in the Olympic pool.
Be careful thou to do not confuse this paradigm (a set of rules and behaviors) with the “quick fix”. The only way to grow yourself is by taking it step by step, accelerated steps, since you learn a lot faster from other’s mistakes!
So what’s stopping you to do it?
