The beginning of every decision is in the mind.
The mind is where we find the tools for every important decision in our lives. Love. Happiness. Success. It is our spirit, however- our heart that puts those tools to use.
Evaluate your mindset. Is there sometime in the day where you contradict your true purposes for something mediocre, in your mind? When you have absolute dominion over your mind, why should you ever make a compromise for something unhelpful or discouraging to enter it?
You're the master of your thoughts. Let them guide you to the end of every dream, rather than condemn you to thinking life is a nightmare. Because, after all, it's never as bad as we make it out to be.
