If you want a significant change in your results, then you probably need a significant change to your strategy. Working harder on your current strategy is unlikely to move the needle.

Before you work harder, work on the right thing.

Play better games. Win better prizes.

There ain't no where else to be 

'Cept right here and I'm stranded 

Van Morrison

Use your health, even to the point of wearing it out. That is what it is for. Spend all you have before you die; and do not outlive yourself.--George Bernard Shaw

It is by extending oneself, by exercising some capacity previously unused that you come to a better knowledge of your own potential.  

Harold Bloom 

Do the best you can until you know better. Then when you know better, do better.

Maya Angelou

The people you meet change your life.

So meet as many people as you possibly can.

Remember, you're always one connection away, from changing your life forever.
