The other day I was at the gym with my buddy who has been training me. In the beginning of the workout I was making excuses and just knew I wasn't giving it my all. Then my friend was tellin me how the gym is difficult because it's a mind game. That really resignated with me because of the truth behind that. Just like in life, you may want to quit or not push through to finish your set (or in life, journey). This is where your mind comes in play. You have to have that "can do" attitude, or like Nike says, "Just Do It."
Im not saying I'm perfect and I have that "Just Do It" attitude always, that'll be a lie. It's definitely something I continue work on daily. Remember success is a journey. We aren't in a sprint, but a marathon. Just remind yourself that you are doing this day by day, getting better and better as you strive to make your dreams into reality.
Self talk is so important. Turn your conscious mind into your success coach. Constantly reminding you what you're playing for and telling you to keep pushing, because "The cave you fear to enter holds the treasure you seek."
