Even if you don't have a coach or a mentor, you can fire yourself up with "positive self-talk." Essentially, this is a pep-talk selfie.
Use positive language to describe what you hope to accomplish today, tomorrow and in the future. Tell it to Hashem and pray for it, too.
Unfortunately, people are constantly using statements that cause them to berate themselves, their efforts, or their abilities. What could be greater self-persecution? They need to learn how to turn these around into positive statements instead. That's where "positive self-talk." You certainly know how to take a selfie with your cellphone camera, right? This is just as easy - give yourself a pep-talk selfie! Make 5 to 10 strong statements that reflect your aspirations and abilities. Share them too with Hashem, and tell Him that you're positive that He hears you and that He'll help you. Do this daily and you'll go a long way.
Don't ever forget though: true personal growth doesn't come easy. In fact, it hurts. But it sure feels great.
