If you tell yourself that YOU CAN'T DO IT then the TRUTH is that YOU WON'T DO IT because YOU WILL NEVER TRY TO DO IT.
After you CONVINCE YOURSELF that it is TOO HARD FOR YOU then YOU ALREADY CONVINCED YOURSELF so YOU WON'T EVER TRY IT.
You may be AFRAID OF HEIGHTS yet if YOU TRY DOING some things that are DONE THAT ARE HIGH then YOU MAY ENJOY DOING THEM.
If you want to ENJOY YOUR LIFE'S JOURNEY then it means that there may be times that you need to TRY THINGS even if YOU THINK IT IS TOO HARD.
There are MANY THINGS that YOU WILL FINALLY TRY that then YOU FIND OUT THAT YOU DON'T LIKE DOING THEM.
But TRYING IT GIVES YOU THE TRUTH about whether YOU CAN OR YOU CAN'T DO IT.
And the TRUTH MAKES YOU HAVE A CHANCE TO KNOW THE WHOLE TRUTH not a FALSE GUESS.
DON'T GUESS just TRY IT so YOU WILL KNOW then forever YOU CAN KNOW THE TRUTH.
