I could deeply connect with what you are saying. Sometimes I look back on how my journey and see how many beliefs kept me where I was instead of getting where I wanted to get.

I've had everyone of those beliefs, except for the 3rd one and struggled for years. But because I didn't give up, I was able to eventually come to a level where I love fitness and achieved my dream body. The journey is everything. You need to fall in love with the process.
