It's my experience that how I think and what I focus on feeds into how I am Being... And that is what makes it important. How I Be(have) moves me further toward what I desire and need, or moves me not, or moves me further away... This is what attracts to me the right people and/or keeps my eyes open to recognizing them as well as the opportunities that move me in the direction I want to go.
That's the mindset I'm striving for in my daily life; there is some real logic in the concept, even at a very basic level. If we're always working towards our desired outcome, it makes sense that we will move closer to it. It seems to be human nature to sabotage ourselves, but maintaining that positive mental attitude can make a massive difference!
It really is a challenge for me sometimes. I try my best. I'm striving for that as well..
As a wise man once said, sloth and steady wins the race. Try not to focus on the negatives and let the good times flow.
