Don’t confuse what you wish were true with what is really true. Don’t worry about looking good—worry instead about achieving your goals.

When encountering your weaknesses you have four choices: 1. You can deny them (which is what most people do). You can accept them and work at them in order to try to convert them into strengths (which might or might not work depending on your ability to change). You can accept your weaknesses and find ways around them. Or, you can change what you are going after.
