When you feel overwhelmed, understand that you need to take a break. The break could be minutes, hours, days, or months. Sometimes you may even take years before inspiration strikes! Regardless of how you feel in a day, remember the difference between success and failure is that you continue to try. Failure, while an option, does not need to be the final step. You can determine your own desires and aspirations. Take time to yourself, but put yourself back in the game. Because as long as you continue, you can succeed. Maybe not today, maybe not tomorrow, but one day you will. And when that happens, you will be proud you did.
Keep up the good work, because you are worth it.
