Never Give up!
Even when you feel like everything is falling to pieces, even when you think that there's no solution to your problem let me tell you that it's never late, it's never late to find a solution, it's never late to be the best!
Remember that reaching your goals is more a matter of attitude and how committed you're to it, don't expect to reach your goals by sitting on the couch all day and not putting some effort to it. Set your goals, where do you see yourself in 2,3,4,5.. days/months/years time?
Most of our failure will come when we "convince" ourselves that we can't do it. Remember this, the moment you set yourself a goal and take the first step, it's 50% done. Of course, the remaining 50% won't be reached as easy as the first 50% but it's definitely not Impossible. Only the people that have reached greatness and success in life didn't give up, take Thomas Edison for example, how many attempts took him to achieve his goal of creating the light bulb? Thousands! And will you give up at the 2nd try? I don't think so!
So picture yourself reaching the goal everyday because one day, it will materialize and come to life.
